A uniform sphere of mass m and radius R is placed on a rough horizontal surface (Fig. 7.9). The sphere is struck horizontally at a height h from the floor. Match the following:

(a) h = R/2(i) Sphere rolls without slipping with a constant velocity and no loss of energy.
(b) h = RSphere spins clockwise, loses energy byfriction.
(c) h = 3R/2(iii) Sphere spins anti-clockwise, loses energy by friction.
(d) h = 7R/5(iv) Sphere has only a translational motion, looses energy by friction.
