A7.28-kilogram bowling ball traveling 8.50 meters per second east collides head-on with a 5.45 kilogram bowling ball traveling 10.0 meters per second west. determine the magnitude of the total momentum of the two-ball system after the collision

Given:

Mass,

Speed,

By using the law of conservation of linear momentum, we get

→

or,

→

By substituting the values, we get

Thus the above approach is correct.
