Question: A 3 0 . 0 kg child slides down a long slide in a playground. She starts from rest at a height h 1 =

A 30.0 kg child slides down a long slide in a playground. She starts from rest at a height h1=25.0m. When she is partway down the slide, at a height h2=10.0m, she is moving at a speed of 5.0ms.
Calculate the change in thermal energy of the system from h1 to h2.
