Physics · LAWS OF MOTION

An impulse of \( 15 \text{ N s} \) is applied to a body of mass \( 3 \text{ kg} \) initially at rest. The final velocity acquired by the body is:

1. A
   \( 45 \text{ m s}^{-1} \)
2. B
   \( 5 \text{ m s}^{-1} \)
3. C
   \( 15 \text{ m s}^{-1} \)
4. D
   \( 2.5 \text{ m s}^{-1} \)
