9. You throw a ball vertically upward and catch it at the height from which you released it. Air resistance is negligible. (a) Compare the time the ball takes to rise with the time the ball takes to fall. (b) Compare the initial and final velocities. (c) What is the instantaneous velocity at the top of the flight? (d) What is the ball's acceleration as it is rising? at the top of the flight? as it is falling? (e) Sketch the position-time graph, the velocity-time graph, and the accelera- tion-time graph for the ball's motion during its flight. Use [up] as the posi- tive direction
