Question

As a protest against the umpire's calls, a baseball pitcher throws a ball straight up into the air at a speed of 17.5 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.

Expert Solution

Step 1

The forces on the ball along the vertical direction will be :

The force exerted by the pitcher, F upwards.
The gravitational force, mg downwards.

Step 2

The work done on the ball due to the resultant force will be

= Resultant force x Distance for which the force is applied

=(F-mg) x d
