A ball is dropped vertically from heigth h and is bouncing elastically on the floor (see figure). Which of the following plots best depicts the acceleration of the ball as a function of time.

A tennis ball is released so that it falls vertically to the floor and bounces again. Taking velocity upwards as positive, which of the following graphs best represents the variation of its velocity v with time t ?

A ball is dropped from a height h. As it bounces off the floor, its speed is 80 per cent of what it was just before it hit the floor. The ball will then rise to a height of most nearly:

A ball is dropped from certain height on a glass floor so that it rebounds elastically to the same height. If the process continues, the velocity -time graph for such a motion would be -

A ball is thrown vertically upwards. Which of the following plots represents the speed-time graph of the ball during its height if the air resistance is ignored ?

A ball is dropped from a height h . As it bounces off the floor, its speed is 80 percent of what it was just before it hit the floor. The ball will then rise to a height of most nearly

A ball is thrown horizontally from a height h above a staircase as shown in the figure. If the coefficient of restitution for any collision between the ball and the staircase is e, then the value of h for which the ball will bounce the same height above each step, is

A ball is thrown vertically upward.Which of the following plots represents the speed-time graph of the ball during its flight if the air resostance is not ignored?
