Question

Determine the coefficient of kinetic friction when the frictional force is 65 N and the normal force is 120 N

Answer 1

Answer:

0.5417

Explanation:

The frictional force is equal to the coefficient of kinetic friction times the normal force, so

$F_f=\mu_kF_n$

Then, solving for the coefficient of kinetic friction, we get:

$\mu_k=\frac{F_f}{F_n}$

Now, we can replace the frictional force Ff by 65 N and the normal force Fn by 120 N

$\mu_k=\frac{65N}{120N}=0.5417$

Therefore, the coefficient of kinetic friction is 0.5417
