Two billiard balls each of mass 0.05 kg ...

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

Text Solution

Verified by Experts


Impulse imparted=change in momentum=m(6+6)=0.05(12)=0.6 kg `ms^(-1)`
