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

Options

A. `0.48 kg-m//s`
B. `0.24 kg-m//s`
C. `0.81 kg-m//s`
D. zero

Answer

A

Explanation

As balls rebound with same speed, hence impulse imparted to each ball `=2p=2mv=2 xx 0.06 xx 4 = 110.48 kg-m//s `
