Q: A uniform sphere of mass m and radius R is placed on a rough horizontal surface (figure). The sphere is struck horizontally at a height h form 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 = R | (ii) | Sphere spins clockwise, loses energy by friction. |
| (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. |
