Train car a is at rest when it is hit by train car b. the two cars, which have the same mass, are stuck together and move off after the collision. how does the final velocity of train cars a and b after the collision compare to the initial velocity of train car b before the collision? the final velocity is double train car bâs initial velocity. the final velocity is the same as train car bâs initial velocity. the final velocity is half of train car bâs initial velocity. the final velocity is zero since train car b will stop.
