When throwing a baseball a force is exerted by the hand, Physics

Assignment Help:

When throwing a baseball, a force is exerted by the hand on the ball.

a. Is this force a contact force or a field force? Contact Force

b. Throwing a ball 6 m straight upwards needs a 25 N throwing force. How strong is the throwing force it experiences when the ball is half way to the top? At the very top? Half way back downwards?

Since throwing is a contact force, once the ball is not in contact with the hand there is no more force. hence, the answer to all is 0 N
