1. The problem statement, all variables and given/known data A high diver(m = 62kg) walks off a platform 15 meters above the water below (assume velocity inital = 0). The diver reaches a depth of 2.2 metres in the pool before coming to a stop. 1. What is the diver's change in kinetic energy (Answer: -9114J) 2. What is the average force of the water pushing up on her? (Answer: 4750 N ... the acceleration corresponds to a about 8 g's) I don't get the correct answer to the first question and I don' know how to attempt the second question. Please help and please show me the steps. 2. Relevant equations Work Energy Theorem 3. The attempt at a solution 1. Change in GPE = Change in KE mgh = change in KE (62kg)(9.8)(17.2m( change in KE = 10450.72, which is the wrong answer.
