A 280-kg flatcar 22 m long is moving with a speed of 6.0 m/s along horizontal frictionless rails. A 95-kg worker starts walking from one end of the car to the other in the direction of motion, with speed 2.5 m/s with respect to the car. In the time it takes for him to reach the other end, how far has the flatcar moved?
