Halliday, Resnick & Walker — Potential Energy and Conservation of Energy: Problem 93
A playground slide is in the form of an arc of a circle that has a radius of 12 m. The maximum height of the slide is \( h = 4.0 \) m, and the ground is tangent to the circle (Fig. 8.53). A 25 kg child starts from rest at the top of the slide and has a speed of 6.2 m/s at the bottom. (a) What is the length of the slide? (b) What average frictional force acts on the child over this distance? If, instead of the ground, a vertical line through the top of the slide is tangent to the circle, what are (c) the length of the slide and (d) the average frictional force on the child?
