3. A 0.145 kg ball moving horizontally at 20 m/s is struck by a bat that causes the ball to move in the
opposite direction at 15 m/s. If the ball and bat were in contact for 5 ms, how much force did the bat
apply to the ball?

Ответ:
F = 1015 N
Explanation:
Given that,
Mass of a ball, m = 0.145 kg
Initial speed, u = 20 m/s
Final speed, v = -15 m/s (as it moves in opposite direction)
The ball and bat were in contact for 5 ms
We need to find the force the bat applies to the bat. We know that,
F = ma
So, the bat will apply 1015 N force to the ball.
