In the lab we saw that we are making the cart move with the help of a battery powered fan attached on the cart. Suppose the track is nearly frictionless and very long. We turn on the fan, let it run for sometime, then turn it off. We see that the cart O gradually slows down and comes to a stop. O gradually slows down and continues with constant velocity. O just continues with constant velocity slows down, stops, then starts going in the opposite direction.
