Two billiard balls each of mass 0.05 kg ...

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

Text Solution

Verified by Experts

Impulse on each ball `= 0.05 xx 12 = 0.6 kg m s^(-1)` in magnitude. The two impulses are opposite in direction
