Document Summary

Q you are running towards another player to meet in a tackle in a game of rugby. In a collision, the total momentum of the system is equal to the sum of the mass * velocity of all the colliding objects. The momentum must remain constant after the collision but how will the players be moving. So the two players will be moving at 1. 8m/s after the collision. Since the value is positive, it measn that they will move in the direction of the player whose velocity was positive. Therefore, 100kg person goes forward and 80kg person goes backwards. You must have a greater momentum going into the collision. If you are smaller you must have a larger velocity or. You must apply force to the ground over a longer period of time so that the ground applies a reaction force into you!
