Is My Calculation of Resultant Force and Acceleration Correct?

[01010011]

I'm I on the right track here?

Homework Statement

Determine the resultant force and acceleration for a box of mass 15kg being pushed with a force of 9N and a force of friction 6N acting to oppose.

Homework Equations

Force = Mass * Acceleration

The Attempt at a Solution

Force = 9N
Resultant Force = 9N - 6N = 3N (is this correct?)

Mass = 15Kg
Therefore,

3 = 15 * A
A = 3/15 m/s (this can't be right, can it?)

Why not? But although your magnitude is correct, your units are off.
