A 30-kg child slides down the amusement-park wave slide shown in Figure P9.29. When they are \(0.95 \mathrm{~m}\) above the water level their speed is \(2.2 \mathrm{~m} / \mathrm{s}\). At the top of the final hump, at a height of \(0.90 \mathrm{~m}\) above the water level, their speed is also \(2.2 \mathrm{~m} / \mathrm{s}\). What is the increase in the thermal energy of the child and the slide as they move between these two points?
