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 $12ms^{- 1}$. If the ball moves linearly, then the impulse imparted to the ball is

• A. $1.8Ns$
• B. $2.8Ns$
• C. $3.6Ns$
• D. $4.2Ns$

Answer 1

Answer: (C)

$3.6Ns$

Answer 2

Change in momentum $= 0.15 \times 12 - ( - 0.15 \times 12)$

$= 3.6Ns$

Impulse $= 3.6Ns$in the direction from the batsman to the bowler
