| Assertion (A): | A body can have acceleration even if its velocity is zero at a given instant of time. |
| Reason (R): | A body is momentarily at rest when it reverses its direction of motion. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
| 3. | (A) is True but (R) is False. |
| 4. | Both (A) and (R) are False. |
| Assertion (A): | Two balls of different masses are thrown vertically upward with the same speed. They will pass through their point of projection in the downward direction with the same speed. |
| Reason (R): | The maximum height and downward velocity attained at the point of projection are independent of the mass of the ball. |
| 1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
