Question

Asked Nov 4, 2019

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 17.0 m/s. In the process, he moves his hand through a distance of 1.45 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.

N

Step 1

**Given:**

Mass of the ball = 0.150 kg

Distance moved by the ball before leaving from the hand = 1.45 m

Intial velocity of the ball = 0 m/s

Final velocity of the ball = 17 m/s

Step 2

Calculating the force exerted b...
