A speeding train (with mass 444,000 kg) is moving east with speed 88.9 m/s. Superman (with mass 90.7 kg) needs to stop the train, (so it doesn't fly off the edge of a cliff!) so he flies directly west toward the train. When he reaches the train, he holds it tightly, and they come to a complete stop in 3.25 s.
