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 1500 kg car starts from rest at the top of the driveway that is sloped at an angle of 30 degrees to the horizontal. An average friction force of 3500 N impedes the car’s motion so that car’s speed at the bottom of the driveway is 4.2 m/s. What is the length of the driveway?
