Question

A batsman hits back a ball of mass 0.15 kg straight in the direction of the bowler without changing its initial speed of 12 $m{s}^{-1}$. If the ball moves linearly, then the impulse imparted to the ball is

• A. 1.8 N s
• B. 2.8 N s
• C. 3.6 N s
• D. 4.2 N s

Answer 1

Answer: (C)

3.6 N s

Change in momentum $+0.15\times 12-(-0.15\times 12)=3.6$ N s
Impulse = 3.6 N s in the direction from the batsman to the bowler.
