Rohit can consistently throw a 0.200-kg ball at a speed of 12.0 m/s. On one such throw, Rohit throws the ball straight upward and it passes the top of a flagpole when it is 6.00 m above the ball's initial position. a. What is the ball's gravitational potential energy when it passes the top of the flagpole? (Assume the ball's initial gravitational energy is 0 J. b. What is the ball's kinetic energy as it passes the top of the flagpole? c. What is the ball's velocity as it first passes the top of the flagpole. d. What is the maximum height to which the ball will rise
