4. A 60 kg student jumps from the 10 meter platform into a pool below. a. What is her velocity at impact with the water. (14 m/s) b. How much kinetic energy does she possess at impact? (5880J) c. Once she is in the water, she comes to a stop in 2.0 m. What is the magnitude of the force that the water exerts on her? (-2940N ) d. What was the change in the PE as she climbed to the top of the 10 m platform? (5880J) e. Compare the KE at impact and the velocity at impact for a 60 kg diver and a 75 kg diver diving from 10 meters. (5880,7350)
