A 10-kg bowling ball moving at 4 m/s bounces off a spring at about the same speed that it had before bouncing. What is the change in momentum of the bowling ball

change in momentum is approximately 0 kgm/s

Explanation: The change in momentum is difference between the momentum before collision and momentum after collision. So since the Velocity after collision is almost the same as that before collision then there will be no change in the momentum since the mass is constant.

Note that momentum is just the product of mass M and Velocity v.

the force represented by vector a is normal force. if the hockey puck is moving to the right, when it is hit with a significant force by the hockey stick the puck will move off in a different direction. correct on edge.
