A football player with a mass of 88 kg and a speed of 2.0 m/s collides head-on with a player from the opposing team whose mass is 120 kg. The players stick together and are at rest after the collision. Find the speed of the second player, assuming the speed of light is 3.0 m/s.© BrainMass Inc. brainmass.com March 4, 2021, 6:21 pm ad1c9bdddf
This is a conservation of momentum problem in the relativistic frame P1 + P2 had to have been zero to start with for the football players to come to rest in the conservative collision. Here following the collision both the system kinetic energy and the momentum are zero.
