The 50,000-lb flatcar supports a 15,000-lb vehicle on a 5° ramp built on the flatcar. If the vehicle is released from rest with the flatcar also at rest, determine the velocity v of the flatcar when the vehicle has rolled s = 40 ft down the ramp just before hitting the stop at B. Neglect all friction and treat the vehicle and the flatcar as particles.
