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

a
0.48 kg-m/s
b
0.24 kg-m/s
c
0.81 kg-m/s
d
Zero

detailed solution

Correct option is A

Impulse = change in momentum = 2 mv             = 2×0.06×4=0.48 kg m​/​s
