A batsman hits back a ball straight in the direction of the bowler without changing its initial speed of \( 12\text{ m s}^{-1} \). If the mass of the ball is \( 0.15\text{ kg} \), determine the magnitude of the impulse imparted to the ball.

1. A
   \( 0\text{ N s} \)
2. B
   \( 1.8\text{ N s} \)
3. C
   \( 3.6\text{ N s} \)
4. D
   \( 7.2\text{ N s} \)
