(Elastic Collision - Conservation of Momentum): A 3000-kg truck moving right with a speed of 10.0 m/s
collides head-on with a 1000-kg car moving left with a
speed of 20.0 m/s. The two vehicles bounce off each
other and the truck moves left at 6.0 m/s. Determine
the velocity of the 1000kg car after the collision. (Do
NOT include units in your answer. Just put the number!)
