Two billiard balls each of mass 0.05 kg moving in opposite directions with speed 6 ms-1 collide and rebound with the same speed. What is the impulse imparted to each ball due to the other ?

Explanation

Momentum before collision
`vec(p )_(1) = mv`
Momentum after collision
`=mv `
`=-0.05 xx 6`
Impulse of force of each ball
`= p_(2) - p_(2)`
`=0.6 kg ms^(-1)`
`:.` Impulse of force of each ball applied in mutually opposite direction =0.6 kg`ms^(-1)`
