Tow does the total momentum of the system after the collision compare with that before the collision? Do your poults agree with your expectations? Explain. Calculate the total kinetic energy, E = Y ., of the system both before and after each of The collisions. Iluw do these entities compare! l'art 2 Inelastic collisions 1. You can use the tables below to help with your analysis of the momentum before and alter the collision.
