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.

Textbook Question

Chapter 7, Problem 42P

GO Figure 7-41 shows a cord attached to a cart that can slide along a frictionless horizontal rail aligned along an xaxis. The leftend of the cord is pulled over a pulley, of negligible mass and friction and at cord height h = 1.20 m, so the cart slides from x₁ = 3.00 m to x₂ = 1.00 m. During the move, the tension in the cord is a constant 25.0 N. What is the change in the kinetic energy of the cart during the move?
