How To Find The Range Of A Cannon Ball

A cannon is positioned with a direction of 60 degrees between the ground and itself. .The shooting velocity is $800\over \sec}$. What is its range?

I didn’t really understand this question. Am I asked how further the cannon ball will go before it descends? Because if so, I should I find the highest point the cannon ball get? Should I do it by differentiating?

I would truly appreciate your assistance.

• $\begingroup$I am confused. I’ve learned so far about acceleration, velocity, gravity and how to find each one by differentiating and integrating. Maybe I need further information?$\endgroup$Apr 18 ’15 at 15:24
• 1$\begingroup$Of course you do need more! There are well known, basic formulas for this: initial velocity, some kind of air resistance , the elevation angle, etc. You must have been given these formulas…or you can find them googing in the net, of course.$\endgroup$Apr 18 ’15 at 15:26
• $\begingroup$Consider vertical and horizontal component separately. Equate time taken.$\endgroup$

In the simplest model, you are working in two dimensions, with the system of equations:

$$\frac = -g \\\frac = 0 \\y=0,y’=\sin s \\x=0,x’=\cos s$$

where $g> 0$ is acceleration due to gravity, $\theta$ is the angle of the initial velocity, and $s$ is the initial speed. Note that this model assumes no friction. When you solve you find

$$y=-\frac gt^2 + \sin s t \\x=\cos s t.$$

In projectile motion, you need to concern yourself with the two components of displacement:

What Is Range In Projectile Motion

The range of the projectile is the displacement in the horizontal direction. There is no acceleration in this direction since gravity only acts vertically. shows the line of range. Like time of flight and maximum height, the range of the projectile is a function of initial speed.

The equations of the motion are applicable separately in x-Axis and the y-Axis for finding the unknown parameters.

R = v02sin2/g

• G = acceleration due to gravity
• = angle of the initial velocity from the horizontal plane

Estimating The Uncertainty In Measurements

Before you combine or do anything with your uncertainty, you have to determine the uncertainty in your original measurement. This often involves some subjective judgment. For example, if youre measuring the diameter of a ball with a ruler, you need to think about how precisely you can really read the measurement. Are you confident youre measuring from the edge of the ball? How precisely can you read the ruler? These are the types of questions you have to ask when estimating uncertainties.

In some cases you can easily estimate the uncertainty. For example, if you weigh something on a scale that measures down to the nearest 0.1 g, then you can confidently estimate that there is a ±0.05 g uncertainty in the measurement. This is because a 1.0 g measurement could really be anything from 0.95 g to just under 1.05 g . In other cases, youll have to estimate it as well as possible on the basis of several factors.

Tips

• Significant Figures:Generally, absolute uncertainties are only quoted to one significant figure, apart from occasionally when the first figure is 1. Because of the meaning of an uncertainty, it doesnt make sense to quote your estimate to more precision than your uncertainty. For instance, a measurement of 1.543 ± 0.02 m doesnt make any sense, because you arent sure of the second decimal place, so the third is essentially meaningless. The correct result to quote is 1.54 m ± 0.02 m.

How To Calculate The Distance To The Object Using Binoculars Range Calculator

To be able to successfully calculate the distance to a given target, use the formula D = H / K, where D is the distance to the target in kilometers, H is the estimated height of the target in meters, and Kis the vertical angle of the target expressed in millimeters. Calculate the distance by first estimating the height of the target. And then measuring the horizontal angle of the target.

Range Of Error Of Measurements

While reporting the mean time of 100 pendulum oscillation with the error.What should be the should be the error range?The one which includes all the data or the shorter one one which include most of the data?And why is it so?

The data I have:$90,91,95,92$ and the least count is 1 sec.

I think the mean should be $92\pm 3$ for it includes all the data.But it is not a short range.

I calculated the standard deviation of data.It came out to be $2.16$

The standard error in the mean is indeed given by the corrected sample standard deviation divided by the square root of the number of points.

For a large sample then you can find a reasonably unbiased estimate of the sample standard deviation by dividing the sum of the variances by $N-1$ and taking the square root. This yields the figure 2.16 in your dataset. However, for $N=4$ this is unlikely to be correct. For normally distributed uncertainties, a better estimate for small $N$ is provided by division by $N-1.5$ .

Thus, in your case: The mean is 92.0

The standard deviation of the population is 2.36 and the standard error would be 2.36/2 = 1.18.

I would probably quote this as $92.0 \pm 1.2$.

How To Solve Any Projectile Motion Problem : Introducing the âToolboxâ method of solving projectile motion problems! Here we use kinematic equations and modify with initial conditions to generate a âtoolboxâ of equations with which to solve a classic three-part projectile motion problem.

Now, letâs look at two examples of problems involving projectile motion.

Absolute Vs Relative Uncertainties

Quoting your uncertainty in the units of the original measurement for example, 1.2 ± 0.1 g or 3.4 ± 0.2 cm gives the absolute uncertainty. In other words, it explicitly tells you the amount by which the original measurement could be incorrect. The relative uncertainty gives the uncertainty as a percentage of the original value. Work this out with:

So in the example above:

The value can therefore be quoted as 3.4 cm ± 5.9%.

3. Does weight affect a Projectile Motion?

Yes, greater the weight of an object the greater the gravity influence on it in case of a Projectile Motion. Gravity stops the upward movement thus pulling the object downwards, thus limits the vertical component of projectile.

4. What is acceleration at a Maximum Height?

At a Projectile’s maximum height the acceleration is zero.

Range Of A Projectile

In physics, a projectile launched with specific initial conditions will have a range. It may be more predictable assuming a flat Earth with a uniform gravity field, and no air resistance.

The following applies for ranges which are small compared to the size of the Earth. For longer ranges see sub-orbital spaceflight. The maximum horizontal distance traveled by the projectile, neglecting air resistance, can be calculated as follows:

d 0 ) }\left}

where

• d is the total horizontal distance travelled by the projectile.
• v is the velocity at which the projectile is launched
• g is the gravitational accelerationusually taken to be 9.81 m/s2 near the Earth’s surface
• is the angle at which the projectile is launched
• y0 is the initial height of the projectile

If y0 is taken to be zero, meaning that the object is being launched on flat ground, the range of the projectile will simplify to:

d }}\sin 2\theta }

Correct Formula To Find The Range Of A Projectile Initial Velocity Initial Elevation And G

I want to find the range of a projectile

Hours of searching have given no useful results. Those that I thought were useful turned out to be incapable of accounting for negative angles. This formula in particular returns a range of 0 if the angle is 0, which simply doesn’t make sense.

For example:

• $\begingroup$is $\theta$ an angle to the horizontal?$\endgroup$

With horizental velocity $v_x=v_0\cos\theta$ and vertical velocity $v_y=-v_0\sin\theta-gt$ and integration we see$$x=\int_0^tv_0\cos\theta\,dt=v_0\cos\theta\,t\,\,\,,\,\,\,y=\int_0^t v_y\,dy=-v_0\sin\theta\,t-\frac12gt^2$$Eliminating $t$ between them gives$$y=-\tan\theta\,x-\fracx^2$$the range $R$ is the point $$ and you may continue from here!

Edit: The solution for $h=-y_0$ and $\theta< 0$ after solving the equation$$\fracd^2+\tan\theta\,d-h=0$$is$$d=-\dfrac\sin2\theta\left$$which works for $\theta< 0$ as you wanted.

Assuming a projectile is launched at angle $\theta$ from horizontal from a height $y_0$ above the ground, where the ground is assumed to be represented by the line $y = 0.$The measurement of the angle is such that $\theta = 0$ if the projectileinitially is moving horizontally to the right, and otherwise the angle is measured in a counterclockwise direction from “horizontal to the right,”so small positive angles are upward and small negative angles are downward.

Horizontal Range Of Projectile Formula Derivation

When a projectile is launched it takes a parabolic path and the range of this parabola is given by the relation

But the question is how did we get this relation for the range of the projectile.

To derive this formula let us consider the figure given below which depicts a ball launched with initial velocity \ that makes an angle \ with the horizontal. This ball then travels in a parabola and we have to work out the range formula from this given information.

We will now break the process of our derivation into three steps for the sake of ease of learning. The summary of these steps is given below in the form of a concept map.

We know that

So, we need two things to get the formula for horizontal range

What Is Meant By Projectile Motion

If a particle or object is thrown nearer to the earth’s surface, the object would move towards the earth’s surface along a curved path with constant acceleration. Such path is known as trajectory or projectile and the motion is known as Projectile Motion.

Examples of Projectile Motion include throwing a cricket ball, angry bird, arrow, or stone in a river, etc. The moment you release them the only force acting on them is gravity and it creates an equal impartial acceleration.
