A hollow sphere of radius 0.200 m, with rotational inertia I =0.0415 kg·m2 about a line through its center of mass,rolls without slipping up a surface inclined at 17.1° to thehorizontal. At a certain initial position, the sphere's totalkinetic energy is 25.0 J. (a) How much of this initial kineticenergy is rotational? (b) What is the speed of the center of massof the sphere at the initial position? When the sphere has moved1.10 m up the incline from its initial position, what are (c) itstotal kinetic energy and (d) the speed of its center of mass?
