A diver of mass 75 kg jumps upward off a diving board and into the water. The
diving board is 2 m above the water.


a. When the diver jumps, she has a speed of 2.5 m/s. How much kinetic energy
does she have? (4 points)

b. How much gravitational potential energy will she have gained at her highest
point? Explain how you found the answer. (3 points)

c. Based on the diver's speed from part (a), how high above the board will she
rise? (4 points)

d. How fast will the diver be moving when she hits the water?
