If two balls each of mass $0.06 \,kg$ moving in opposite directions with speed $4 \,m/s$ collide and rebound with the same speed, then the impulse imparted to each ball due to other is ........... $kg-m/s$

A

$0.48$

B

$0.24 $

C

$0.81$

D

$0$

Solution

(a)Impulse = change in momentum $= 2 \,mv$
=$2 \times 0.06 \times 4 = 0.48\;kg\;m/s$
