Question

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

Answer 1

0.5417

Step-by-step 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=(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=(65N)/(120N)=0.5417`

Therefore, the coefficient of kinetic friction is 0.5417
