A smooth ball is released from rest from a height h as shown in figure. It slides down the first inclined plane and collides with the second inclined plane. a. If e = 0 , find the speed of the ball just after leaving the inclined plane 1. b. If the particle mioves horizontally just after the collision find e .

A steel ball is dropped from th roof of a building. A man standing in front of a 1-m high window in the building notes tha the ball takes 0.1 s to the fall from the top to the boottom of the window. The ball continues to fall and strikes the ground. On striking the ground, the ball gers rebounded with the same speed with which it hits the ground. If the ball reappears at the bottom of the window 2 s after passing the bottom of the window on the way down, dind the height of the building.

A ball is dropped from a height of 20 m and rebounds with a velocity which is 3/4 of the velocity with which it hits the ground. What is the time interval between the first and second bunces (g=10m//s^(2))

A ball is released from a height and it reaches the ground in 3 s. If g=9.8 "m s"^(-2) , find the value of the height from which the ball was released.
