A sphere of radius r and mass m is projected along a rough horizontal surface with the initial velocities indicated. If the final velocity of the sphere is to be zero, express, in terms s of v0, r, and μk,

(a) The required magnitude of ω0,

(b) The time t1 for the sphere to come to rest,

(c) The distance the sphere will move before coming to rest.
