94. A snowboarder oscillates back and forth along a semicircular "half-pipe" of radius 8.0 m (Figure GP 7.94), rising to a maximum height h, as shown. (a) Find the snowboarder's maximum speed if h = 8.0 m. (b) Does the oscillation period depend on h? Explain. (c) Compute the period of small oscillations (h < < 8.0 m).
