A wooden wheel of radius R = 24.0 cm is initially rotating clockwise at 12.0 rev/s and not translating. The wheel is lowered onto a horizontal surface, where the coefficient of kinetic friction is Hk = 0.210. Initially, the wheel slips as it rolls along the surface, but after some time t, it begins to roll without slipping. What is the time t, in seconds? Justify your answer with your rationale and equations used. Isphere =MR Iaisk = MR Ihoop = MR?
