A hollow sphere of radius 0.230 m, with rotational inertia I =0.0323 kg·m2 about a line through its center of mass, rolls withoutslipping up a surface inclined at 10.2° to the horizontal. At acertain initial position, the sphere's total kinetic energy is 13.0J. (a) How much of this initial kinetic energy is rotational? (b)What is the speed of the center of mass of the sphere at theinitial position? When the sphere has moved 1.40 m up the inclinefrom its initial position, what are (c) its total kinetic energyand (d) the speed of its center of mass?
