Concept explainers

Static and Kinetic Friction

Kinetic friction comes into existence when there are moving surfaces means in other words we can say that the force which comes into existing between moving surfaces is known as kinetic friction.

Question

A 20-Mg train is traveling at a speed of 50 m/s at an angle of 10^o. But the driver noticed that the bridge 300-m ahead is missing. At once, he pulls the break, thus applying a frictional resistance of F_f = 1000 N. At the same time Super Botting pushes back the train with a force of F_s=(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.
