Question

You serve a volleyball with a mass of 2.1 kg.the ball leaves your hand with a speed of 30 m/s.

Answer 1

F=?

M= 2.1 kg

A= 30 m/s

F= M*A

F= 63

Answer 2

You haven't asked any question about this situation, so we have to guess.  Perhaps the question is: Why are you playing the game with a ball that weighs more than 4.6 pounds, and how can you protect your hand when it's your serve ?
