ELASTIC COLLISION OF CARS

A bumper car with a mass of 225kg moves with a velocity of 2.8m/s towards a second 227kg car sitting at rest. After an elastic collision, the first car moves off in a direction at an angle 42degrees from its original direction. The second car moves off in a direction perpendicular to the first. Find the final velocity of the SECOND car.A bumper car with a mass of 225kg moves with a velocity of 2.8m/s towards a second 227kg car sitting at rest.
