Impulse — Bat and BallMediumQuestion 30538

Question

A cricket ball (0.15 kg) travels at 30 m/s and after being hit by a bat moves at 40 m/s in the opposite direction. Impulse of the bat on the ball is:
  1. A
    1.5 N·s
  2. B
    4.5 N·s
  3. C
    10.5 N·s
    Correct
  4. D
    15 N·s

Correct answer

10.5 N·s

Explanation

Impulse = Δp = m(v_f − v_i) = 0.15×(40 − (−30)) = 0.15×70 = 10.5 N·s.
