Walker, Halliday & Resnick — Potential Energy and Conservation of Energy: Problem 54

54 A child whose weight is 267 N slides down a 6.5 m playground slide that makes an angle of 20° with the horizontal. The coefficient of kinetic friction between slide and child is 0.10. (a) How much energy is transferred to thermal energy? (b) If she starts at the top with a speed of 0.457 m/s, what is her speed at the bottom?

📝 Solution Approach

Given: 54 A, 267 N, 6.5 m, 0.457 m

Find: (a) How much energy is transferred to thermal energy?; (b) If she starts at the top with a speed of 0
