Two billiard balls each of mass `50g` moving in opposite directions with a speed of `36km//h` colide and rebound with the same velocity What is the impulse imparted to each ball due to other ?

Answer

`kg ms^(-1)` .

Explanation

Impulse imparted to each ball = change in linear
momentum of each ball
`= 2 m upsilon = 2 xx (50 xx 10^(-3)) xx 10`
= 1 kg `ms^(-1)` .
