As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 19.0 m/s. In the process, he moves his hand through a distance of 1.10 m. If the ball has a mass of 0.150 kg, find the force he exerts on the ball to give it this upward speed.

Ответ:
Explanation:
Given data
Initial speed vi=0 m/s
Final speed vf=19.0 m/s
Δy=1.10 m
Mass of ball m=0.150 kg
To find
Force
Solution
First we need to find acceleration of the ball.So we can apply:
vf²=vi²+2aΔy
vf²=0+2aΔy
Because we get the acceleration of the ball.We can now find the force the players exerts on the ball by using Newtons second law
