A rubber ball is throuwn, after touching the ground it jumps again and again and forms a series : 100,90,80… then which is the term in the series when the ball will be at rest.

A ball is thrown from ground vertically upward, reaches the roof of a house 100 meters high. At the moment this ball was thrown vertically upward, another ball is dropped from rest vertically downward from the roof of the house. At which height from the ground do the balls pass each other and after what time?

A ball is dropped from a height 100 m on the ground. If the coefficient of restitution is 0.2, the height to which the ball will go up after it rebounds for the II^(nd) time.

A ball is thrown horizontally with speed 20 m//s from a tower of height 80 m . (a) After how much time and at what horizontal distance from the foot of tower it strikes the ground. (b) Find the magnitude and direction of the velocity with which it strikes the ground. ( c) Find the velocity vector of ball after 1 s . (d) Trajectory followed by the ball.

A small ball is released from rest and it accelerates due to gravity, after 1 sec suddenly gravity disappears and again appears after 5 sec Ball takes total 8 sec to reach the ground. The height above ground from where ball was released is?

When a ball is dropped from a certain height h , it robounds from the ground , strikes again and rebounds again , a number of times before finally coming to rest . If the coefficient of restitution is e , find the height to which it robunds after p^(th) collision ..

A ball is thrown upwards with a speed of 20m/s from the ground. Another ball is dropped from rest from a building 80m high at the same time (i) Find the difference in their height after they have fallen for 2s? (ii) If the balls are along the same line of motion, when will they colide?

A ball starts falling freely from a height h from a point on the inclined plane forming an angle alpha with the horizontal as shown. After collision with the incline it rebounds elastically off the plane. Then it again strikes the incline at

A shot putter with a mass of 80kg pushes the iron ball of mass of 6kg from a standing position accelerating it uniformly form rest at an angle of 45^(@) with the horizontal during a time interval of 0.1 seconds. The ball leaves his hand when it 2m high above the level ground and hits the ground 2 seconds later (g =10m//s^(2)) . The horizontal disatnce between the point of release and the point where the ball hits the ground .
