A child moves from the top to the bottom of a slide. The child's weight is 300 N and acts vertically downwards. The vertical distance from the top to the bottom of the slide is 2.4 m.
The child's kinetic energy store increases by 480 J. Ignore air resistance.
Calculate the work done by the child's weight.
Calculate the increase in the thermal energy stores of the child and the slide. Explain your answer.
