In being served, a tennis ball is accelerated from rest to a speed of m/s. the average power generated during the serve is 2920 w. assuming that the acceleration of the ball is constant during the serve, find the force acting on the ball.

You didn't include the numerical value of speed. 

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
