Question
Two billiard balls each of mass 0.05kg moving in opposite directions with speed 6m/s collide and rebound with the same speed. What is the impulse imparted to each ball due to other
Solution
Impulse (I) = Change in linear momentum
Initial momentum of ball ( both) = mv =
0.05×6 = 0.30 Kg m/s
Final momentum of both balls = -(0.05×6)Kg-m/s .
here minus sign is because the direction of final momentum is just opposite to the direction of initial momentum (linear momentum is a vector )
Now impulse imparted to each ball ;
I = -0.30 - ( 0.30) = -0.60 Kg-m/s
