#### Answer:

The coefficient of friction is

#### Explanation:

The coefficient of kinetic friction is

The normal force is

Initial velocity is

Final velocity is

Distance is

We apply the equation of motion

The negative sign indicates that it is a deceleration.

According to Newton's Second Law,

Therefore,
