A 20-Mg train is traveling at a speed of 50 m/s. 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 = [312d+100] N, where d is the distance that the train travels before stopping. Determine the stopping distance d, and mention whether or not Super Botting would be able to save the train.
