Explanation:
It is given that,
Initial height of the ball,
As it stops, its position, x = 0
It is in contact with the ground for 19.0 ms before stopping,
Initial speed of the ball, u = 0
(a) Let a is the acceleration of the ball during the time it is in contact with the ground. Its can be calculated suing equation of kinematics as :
a =-g
v = 18.25 m/s
(b) The average acceleration can be calculated as :
As the value of acceleration is positive, so the ball is accelerating in upward direction.
