Two train cars of identical mass 10 Kg each collide and move off in opposite directions. The first car was initially traveling at 2.0 m/sec and the other car was initially at a velocity of 3.0 m/sec left. After the collision, the first car is traveling at a velocity of 2.5 m/sec as it moves to the left. What is the final velocity of the other train that is traveling in the opposite direction?
