A disk of mass m = 5 kg, Ic =mR3, and outer radius Ro = 0.9 m contacts an inclined surface with friction coefficient u = 0.15 and ramp angle 0 = 36.8699°. An inextensible, R. B massless string is wrapped around an inner hub of radius R, = 0.6 m. Use a work-energy argument to find the speed of the disk's center after the disk has moved d = 2 meters downhill. Ans: ve = 2.3537 m/s u = 0.15
