Question

A hollow ball with mass m = 0.1 kg and radius R = 5 cm is sliding across a flat frictionless surface

with an initial speed v = 5 m/s. At x = 0, it encounters a patch of ground with coefficient of kinetic

friction μk = 0.3. The ball is initially not rotating but the friction causes it to start spinning. How

far will it travel along that surface before it begins rolling without slipping. For this problem, assume

g = 10 m/s .

(a) 1.5 m (b) 2.7 m (c) 5.7 m (d) 8.3 m (e) 6.1 m
