Question #40973
2 Answers
Collision.
Explanation:
When you have a collision (elastic or inelastic) momentum is conserved.
You have to remember that to have conservation your system must be isolated so that no mass enters or exits (you do not want something such as a rocket burning fuel and loosing mass continuously). Also you need that the resultant of all the external forces must be zero (only internal forces operating).
Collision.
Explanation:
When you have a collision (elastic or inelastic) momentum is conserved, i.e., the total momentum before (initial) will be equal to the total momentum after (final).
You have to remember that to have conservation your system must be isolated so that no mass enters or exits (you do not want something such as a rocket burning fuel and loosing mass continuously). Also you need that the resultant of all the external forces must be zero (only internal forces operating)
