While falling down, initial velocity = 0, final velocity = v, acceleration due to gravity = 9.8 m/s2, height = 5 m
The velocity of the ball with which it hits the ground can be found using,
v2 = u2 + 2as
=> v2 = 0 + 2×9.8×5
=> v = 9.9 m/s (downward)
While it moves up, initial velocity = u, final velocity = 0, acceleration due to gravity = 9.8 m/s2, height = 3.2 m
The velocity of the ball with which it leaves the ground can be found using,
=> 0 = u2 - 2×9.8×3.2 [this time the velocity and acceleration are oppositely directed so we have the negative sign]
=> v = 7.91 m/s (upward)
So, Change in velocity = 7.91 m/s (upward) – 9.9 m/s (downward)
=> Δv = 7.91 m/s + 9.9 m/s [both in upward direction]
=> Δv = 17.81 m/s
So, acceleration is, a = Δv/Δt = 17.81/0.036 = 494.7 m/s2
