Question: A 2 5 0 - k g flatcar 2 5 m long is moving with a speed of 5 . 5 m s along horizontal

A 250-kg flatcar 25 m long is moving with a speed of 5.5ms along horizontal frictionless rails. A 80 kg worker starts walking from one end of the car to the other in the direction of motion, with speed 2.0ms with respect to the car.
Part A
In the time it takes for him to reach the other end, how far has the flatcar moved?
