Two barges, each with a displacement (mass) of 550 Mg, are loosely moored in calm water. A stunt driver starts his 1650-kg car from rest at A, drives along the deck, and leaves the end of the 15° ramp at a speed of 62 km/h relative to the barge and ramp. The driver successfully jumps the gap and brings his car to rest relative to barge 2 at B. Calculate the velocity v2 imparted to barge 2 just after the car has come to rest on the barge. Neglect the resistance of the water to motion at the low velocities involved.
