A ball is dropped from a height of 90 m on a floor At each collision with the floor, the ball loses one tenth of its speed. Plot the speed -time graph of its motion between `t = 0` to 12 s

A ball is dropped from a height of a height of 90 m on a floor. At each collsion with the floor , the ball loses one - tenth of its speed . Plot the speed -time graph of its motion between t 0 to 12 s.

A ball is dropped from a height of 80 m on a floor. At each collision, the ball loses half of its speed. Plot the speed-time graph and velocity-time graph of its motion till two collisions With the floor. [Take g=10 m//s^2 ]

A body dropped from a height h into the floor makes elastic collision with the floor. The frequency of oscillation of its periodic motion is

A ball is dropped from a height of 20 m on a floor for which e = 1//2 . The height attained by the ball after the second collision

A ball is dropped from a height h on to a floor. If in each collision its speed becomes e times of its striking value (a) find the time taken by ball to stop rebounding (b) find the total change in momentum in this time (c) find the average force exerted by the ball on the floor using results of part (a) and (b).
