You toss a ball straight up into the air. Assume that air resistance is negligible.
PART A. Draw a free-body diagram for the ball at three points: on the way up, at the top, and on the bottom, and on the way down. Specifically identify the forces and agents acting on the ball.
PART B. What is the ball's velocity at the very top of the motion?
PART C. What is the ball's acceleration at this point?
