5. A railroad flatcar of mass Me can roll without friction along a straight horizontal track as shown in the diagram. Initially a man of mass Mm is standing on the car which is moving to the right with a speed of vegi. What is the change in velocity of the car if the man runs to the left so that his speed relative to the car is vmef just before he jumps off at the left end? cgi
