Awater park rider (mass = 20.0 kg) starts from rest at the top of a 38.0-m tall water slide (A). The height at B is 14.0 m. Assuming mechanical energy conservation, determine the potential energy (PE) and kinetic energy (KE) values at locations A, B and C. Use 9 = 9.8 leg. Tap on an energy box to enter or edit its value.
