A cannon and a supply of cannon balls are inside a sealed rail road car. The cannon fires to the right, the car recoils to the left. The canon balls remain in the car after hitting the far wall. Show that no matter how the cannon balls are fired, the rail road car cannot travel more than `L`. assuming it starts from rest.

A ball hangs from a string inside a rail road car moving along a straight track. The string is observed to be inclined towards the rear of the car making a constant small angle with the vertical. It shows that the car is

y=-5t^(2)+2t+20 x=2t A cannonball is shot out of a cannon at a 45^(@) angle with an approxiate speed of 283m/s. The cannon from which the ball was fired sits on the edges of a cliff, and its height above the ground is 20 meters. The equations given above represent the cannonball's height above the ground(y) and its horizontal distance (x) from the face of the cliff, t seconds after the ball was fired, where tge0 . How many seconds after the ball was fired does its vertical height above the ground equal its horizontal distance from the cliff?

A cannon-ball is fired with a speed 50 m//sec with respect to ground from one end of a stationary railroad car which rests on a smooth track. The ball collides with opposite wall and stops. How much distance did the railroad car cover just before the collision? Given that the ratio of the mass of the ball to that of the railroad car is 1//99 and the length of the car is 50m

Two 20 kg cannon balls are chained together and fired horizontally with a velocity of 200 m//s from the top of a 30 m wall. The chain breaks during the flight of the cannon balls and one of them strikes the ground at t=2s , at a distance of 250 m from the foot fo the wall, and 5 m to the right of line of fire determine the position of the other cannon ball at that instant Neglect the resistance of air.
