A fullback with a mass of 101 kilogram and a velocity of 5.2 meter per second due west collides head-on with a defensive back with a mass of 93 kilogram and a velocity of 4.9 meter per second due east.
a) Obtain the initial momentum of each player?
b) Obtain the total momentum of the system before collision?
c) If they stick together and external forces can be ignored, find what velocity (magnitude and direction) will they be traveling immediately after they collide?
