Q.
Two billiard balls each of mass $0.06\, kg$ moving in opposite directions with speed $5 ms^{-1}$ collide and rebound with same speed. The impulse imparted to each ball due to the other are
Solution:
Impulse on each ball = $\Delta\,p$ = $0.06 × 10 = 0.6kgms^{-1}$ The two impulses are in opposite direction.
