Special Relativity

The theory of special relativity discusses how space and time are related to objects traveling along a straight line at a constant speed. Simply stated, as an object reaches the speed of light, its mass becomes infinite and it is unable to move faster than light. This interstellar speed limit has been the topic of much debate in astronomy, and also in science fiction when people consider how to fly over large distances.

A 20-Mg train is traveling at a speed of 50 m/s at an angle of 10o. But the driver noticed that the bridge 300-m ahead is missing. At once, he pulls the break, thus applying a frictional resistance of Ff = 1000 N. At the same time Super Botting pushes back the train with a force of Fs=(123)d +100, where d is the distance that the train travels before stopping. Determine the stopping distance d, and mention whether or not Superperson would be able to save the train.
