A 16.0-kg enters a water slide that has a entrance 2.50 m above the ground exit. When the child exits, her speed is 3.50 m/s. What is the potential energy of the child when entering the slide? How much energy is lost due to friction during the water slide trip? If the coefficient of kinetic friction is 0.40, and the entire slide took a time of .50 s, then how much power did friction consume during the slide?
