A force that is present between two moving objects or surfaces is called kinetic friction. It is estimated in newtons (N) and is calculated by:

$\rm F_{k} =\rm \mu _{\rm k} F_{n}$

Where, $\rm F_{k}$ = frictional force, $\mu _{\rm k}$ = coefficient, $\rm F_{n}$ = normal force.

The kinetic friction of the object is 6N.

The kinetic friction can be estimated as:

Given,

Coefficient of kinetic friction ( $\mu$ ) = 0.2Normal force $\rm F_{n}$ = 30 N

Substituting values in the formula:

$\rm F_{k} =\rm \mu _{\rm k} F_{n}$

$\begin{aligned}\rm F_{k} &= 0.2 \times 30\\\\\rm F_{k} &= 6 \rm N\end{aligned}$

Therefore, 6N is the frictional force.

Force of kinetic friction, Fk = 6N

Explanation:

Given the following data;

Coefficient of kinetic friction, μ = 0.2

Normal force, Fn=30N

To find the Force of kinetic friction;

Mathematically, the force of kinetic friction is given by the formula;

Fk = μFn

Where;

Fk represents the force of kinetic friction. μ represents the coefficient of friction. Fn represents the normal force.

Substituting into the equation, we have;

Fk = 0.2*30

Fk = 6N

Therefore, the force of kinetic friction is 6N.
