An elastic ball os mass M is dropped from the height h above the floor. At the instant the ball is at the height h/2, it is struck by a bullet of mass 0.2M, flying horizontally at the speed v. The bullet gets stuck inside the falling ball. The ball then bounces off the floor several times. What is the horizontal distance x traveled by the ball between the first and second bounce? The acceleration due to gravity is g....
A ball is dropped from a height h and bounces. the coefficient of restitution at each bounce is e. Find the velocity immediately after the first bounce, and immediately after the nth bounce. Show that the ball finally comes to rest after a time 3 1 +e /2h
INCREASING TIME > 6) Consider a ball that is dropped from rest from a height of 1.0 meter above the floor. It starts at rest, then speeds up, suddenly reverses direction, and then slows as it rises. Suppose it bounces off the floor and rises back up to a height of 1.0 m (it is a super super- ball). Sketch x, y, vr, and Vy vs. time graphs of this motion (on a separate sheet ofpaper), as illustrated in the...
2) A ball is dropped from rest at a height H. At height h (below H) the ball bounces off a surface with no loss in speed. The surface is tilted at 45°, so the ball bounces off horizon- tally. Derive an expression for the distance the ball travels in the horizontal direction. Plot the distance traveled in the horizontal direction as a function of h where h varies between 0 and H. Nest dropped from H sorface (6 at...
Allison throws a tennis ball at time t = 0 from a height h above the ground equal to her own height. We assume that the positive horizontal direction is the positive x-direction, and the positive vertical direction is the positive y-direction. The ball has a positive initial horizontal velocity vx, and no initial vertical velocity. At times t1 and t2, the ball bounces on the ground for the first, and second times respectively after being thrown. We assume that...
A ball is dropped from a height 24 m above the ground at t=0.0. Each time it bounces from the ground, its rebound speed is 60% of its impact speed. At the instant the first ball hits the ground, a second ball is released from the same place. Take g = 9.8 m/s2. At what height above the ground will they collide? (Take the ground as y=0.0 m)

A ball is dropped from rest at a height h. Directly below on the ground, a second ball is simultaneously t thrown upwards with a speed of vc. The two balls collide at the moment that the second ball is instantaneously at rest. (They collide when the second ball is at its maximum height.) What is the height of the collision? At what time does the collision occur if both balls' motion stated at t = 0 s?
1. A rock is dropped from a bridge that is 15 m above the surface of the river. How long does it take for the rock to hit the water? 2. A ball is thrown upward from the edge of the roof of a 20 m tall building with an initial velocity of 15 m/s. a) What is the maximum height reached by the ball? b) How much time does it take for the ball to reach the ground? c)...
A golf ball is dropped from rest from a height of 8.10 m. It hits the pavement, then bounces back up, rising just 6.10 m before falling back down again. A boy then catches the ball when it is 1.50 m above the pavement. Ignoring air resistance, calculate the total amount of time that the ball is in the air, from drop to catch.
