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 91 kg janitor wearing running shoes is running across an ice rink at a
speed of 3.2 m/s. They try to stop abruptly, but keep sliding across the
surface of the ice. The ice exerts a frictional force of 13.4 N to slow them
down. How far do they travel before halting to a stop?
