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 $12 \,ms.$ 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. $4.2\,Ns$

Answer 1

Answer: (C)

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