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

Tardigrade Admin · Accepted Answer

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

Q. A batsman hits back a ball of mass $0.15 k g$ straight in the direction of the bowler without changing its initial speed of $12 m s .$ If the ball moves linearly, then the impulse imparted to the ball is

$1.8 N s$

$2.8 N s$

$3.6 N s$

$4.2 N s$

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.
