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 rock is dropped from a height of 110 meters above the ground. One second later, a ball is thrown vertically downward from the same height with an initial speed of 14 m/s. A. At what time after the ball if thrown are the two objects at the same height above the ground? B. What is the speed of the rock when the ball hits the ground?

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?

A 0.2 Kg ball is dropped with no initial velocity from a height of 6 m. It drops vertically with no air drag, it hits the flat, concrete ground and re-bounces upward in a vertical direction reaching a maximum height of 4 m. (i) Calculate the speed of the ball when it hit the ground. (ii) Calculate the speed of the ball when it began moving upward. (iii) Calculate the magnitude of the impulse provided by the ground to the...

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....
