Consider a system to be one train car moving toward another train car at rest. when the trains collide, the two cars stick together. what is the total momentum of the system after the collision? before collison car 1 car 2 m1 =600kg m2 =400kg v1 =4 m/s v2 =0 m/s choices: 800kg × m/s 1,600kg × m/s 2,400kg × m/s 4,000kg × m/s someone ! the lady who tought me did a terrible job of explaining how to do this!
