#### Answer:

The total force is composed of two pieces: the force required to accelerate the mass and the force required to overcome friction.

#### Explanation:

The total force is made up of two different forces.

If there were no friction, the force required to accelerate a mass of

The second part is the frictional force:

To find the total force, just add these two forces:
