You drop a \(0.05 \mathrm{~kg}\) tennis ball from rest and it takes \(0.5 \mathrm{~s}\) to hit the ground.
(a)
Use the Impulse-Momentum theorem to find the velocity of the ball just before impact with the ground.
(b)
The tennis ball rebounds from the ground with the same speed as impact. The collision takes \(0.01 \mathrm{~s}\text{.}\) Find the average net force on the tennis ball.
