A \(20-\mathrm{kg}\) child runs up the amusement-park wave slide shown in Figure P9.29. When she is nearly at the top of the first hump, which is \(0.90 \mathrm{~m}\) above the water, she flops down and slides over the top of the hump at \(1.5 \mathrm{~m} / \mathrm{s}\). She slides down the other side of the hump and then up the slide, until she reverses motion at a height of \(0.95 \mathrm{~m}\) above the water. What is the increase in thermal energy of the child and the slide due to the sliding from the top of the hump to the top of her motion?
