A cannon (at the origin) shoots a ball at an angle \theta above the horizontal ground. Neglect air resistance. Let r(t) denote the ball's distance from the cannon. What is the largest possible value of \theta if r(t) is to increase throughout the ball's flight? Taylor, Classical...

Hello fellow forum trolls, I am currently pondering about this physics problem that was assigned to me on a day I was not in school and I have some confusion on the process in which to solve it. Essentially we have to cannon out a metal ball through a hoop a certain distance away. We...

A projectile of mass 0.552 kg is shot from a cannon, at height 7 m, with an initial velocity vi having a horizontal component of 5 ms. The projectile rises to a maximum height of Y above the end of the cannon's barrel and strikes the ground a horizontal distance X past the end of the...

Homework Statement Imagine a cannon that is free to roll on wheels. Initially, both the cannon and cannonball are at rest. When the cannonball is fired, though, the momentum transferred to the cannonball comes at the expense of the cannon, so the cannonball and cannon end up with momenta...

This is the question: A physics lecture demonstration uses a small canon mounted on a cart that moves at constant velocity v across the floor. At what angle theta should the cannon point (measured from the horizontal floor of the cart) if the cannonball is to land back in the mouth of the...

http://img263.imageshack.us/my.php?image=helpxy5.jpg (pic attached) Questions: How far did man travel? What was velocity upon hitting the wall? ( is it sufficent to cause death) Known: Time from cannon shot --> impact = 14 seconds ( on pic it says 16, but its actually 14) Angle of...

I have played chess since childhood. I know the absolute value of protecting the king and the relative gain on occasion of sacking a queen. I also know the value of being on the front lines. Indespensible. So I was wondering if anyone knew by breakdown among the casualties by rank? what has been...

A cannon shoots a shell straight up. It reaches its maximum height, 875 feet, and splits into two pieces, one weighing 3 lb and the other 5 lb. The two pieces are observed to strike the ground simultaneously. The 5 lb piece hits the ground 1,659 feet away from the explosion (measured along the x...

Hmm, i have this cenario, there is a cannon and it's target, separated by a distance d, not necessaraly in the same heigh. what i need is a function that gives the velocity needed for the cannon ball reaches the target. PS: consider the angle 45°, there is wind velocity, but not air...

the question is how far away was a cannonball fired? we know that the -cannonball ricocheted along the ground an unknown amount of times before hitting the persons kneecap and shattering it. -a three pound cannon ball has a mass of 1.36kg -the maximum range of the cannon is 1125m -the...

A cannon shoots a projectile at an angle of 60 degrees above the horizontal with an initial speed of 30.0 m/s. A) calculate the maximum height of the projectile and its range ( the horizontal distance traveled when the projectile hits the ground). B) repeat the calculations of part A...

Question: Suppose a cannon is propped against a massive tree to reduce recoil when it fires. Then the range of the cannonball will be a) increased b) decreased c) unchanged My Answer: I am leaning (no pun intended) on a. Since the cannonball exerts a force on to the cannon, it recoils...

I am not too sure whether I am doing this correctly. The problem is basically a mini-cannon aimed at a 60 degree angle, hits a target on the ground 0.8m away. I am suppose to find the initial velocity. This is what I did: Cut the distance in half, assuming the mini cannon-ball will reach...

Someone was fired 47 meters from a cannon. What is th einital muzzle velocity of the cannon? Am I supposed to assume max range which puts the cannon at 45deg?

Okay. we were given a problem in Physics class regarding a PVC pipe, a potato and a piece of dowling(wood) we were instructed to stick both ends of the pipe into the potato and then (once we had a good plug in either end) push one plug towards the other through the pipe with the piece of...

A 1250 kg cannon, which fires a 55 kg shell with a speed of 566 m/s relative to the muzzle, is set at an elevation angle of 39° above the horizontal. The cannon is mounted on frictionless rails, so that it recoils freely. What is the speed of the shell with respect to the Earth...

Hello all, I've searched and browsed and I haven't found anyone else that's asked this question, so I will ask it here. A cannon point at a fixed angle of 30° is placed on a slope of 12° and fired uphill at an initial velocity of 30 m/s. What is its range? I thought about making the...

Hi i was wondering if you guys could help me out on this i think i know the result but i would like to see if your guys agree. heres the situation: A cannon is positioned vertical on top of a moving train, the cannon shoots the ball straight up in the air. Where does the ball land, behind...

Ok now I am new to the whole physics thing so that's y I am here. Ok well I know that there is a fomula that the US army has developed to figure out the elevation in degrees that a cannon should be pointed to land a round on a specefic target, But I am having a problem finding this formula. I...

I was trying to figure out the best angle to shoot a cannon, with air resistance in the differential equation. I came up with ~36.5 degrees, is that right?

ok... So, we see the sun everyday, right? So let's say you are standing on one point of the Earth looking at the sun rise... At where must you point a laser cannon in order to hit the sun dead centre? and why? :confused:

A pumpkin of mass 5kg is shot out of an air cannon at an elevation angle of 45 degrees with an initial velocity of 54m/s. It lands 142 m away. Assuming the force due to air resistance was F=-kmv, find the value of k. I need some help with this problem. I'm not quite sure how to put in the...

Hey everyone, I'm doing a lab for engineering class, and I'm having a little trouble with a part of it. The lab was that we have a cannon on a table, with 3 launch settings (different lengths the spring is compressed). The table is 40" high. Also, we have a dixie cup 90" away from the table...

I understand that if you drop a cannonball from a hole drilled through the Earth from pole-to-pole, the ball would reach a speed of 18,000 mph at the center, and then slow to a speed of zero at the other end of the hole. Can anyone give me a mathematical explanation of this? thanks
