Question

A baseball player friend of yours wants to determine his pitching speed. You have him stand on a ledge and throw the ball horizontally from an elevation 7.00 above the ground. The ball lands 20.0 away.

As you think about it, you’re not sure he threw the ball exactly horizontally. As you watch him throw, the pitches seem to vary from 5° below horizontal to 5° above horizontal. What is the range of speeds with which the ball might have left his hand? What is the minimum and maximum speed of the ball?

Explanation / Answer

Vmin = 15.0238 m/s Vmax = 19.395 m/s
