A body with a mass of m = 20 kg moves uniformly and rectilinearly along a horizontal surface. coefficient of friction 0.2. what is the value of the friction force acting on the body.

It is known from the condition that a body with a mass of m = 20 kg moves uniformly and rectilinearly along a horizontal surface. It is also known that the coefficient of friction is 0.2. It is necessary to find the value of the friction force acting on a given body.

Let’s start with the fact that we will determine that if the body moves uniformly, then the thrust force is equal to the friction force.

Let’s apply the formula to find the friction force:

F friction = k * m * g.

It remains to substitute the values and make calculations, where g = 10 m / s ^ 2.

Friction = 0.2 * 10 * 20 = 40 N.
