Question

Two billiard balls of mass 50g moving in opposite directions with speed of 16m/s collide and rebound with same speed.what is impluse imparted by each ball to the other?

Answer 1

Impulse = change in movementum
Impulse = mv- mu
Here m = 0.05 kg
V =16 m/s
U = - 16m/s
Impulse = 0.05 * 16 - 0.05*(-16)=0.8+0.8=1.6 N *s
