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.

Correct answer

1

Step-by-step solution

Acceleration is all the time (- g ) except at the time of collision it is impulsive force in (+)ve decrease.
