A 6 kg bowling ball rolling at 5 m/s strikes a stationary 4 kg bowling ball
Homework Answers
Final momentum is therefore 30
30 = 6*2 + 4*v
4 v = 18
v = 4.5 m/s forward
However there is a change of momentum or impulse for Ball 2 of 18 kg m/s
Force = change of momentum or impulse / time
=18/.5 = 36 Newtons
