Newton's second law:

$\overline{){\mathbf{\Sigma}}{\mathbf{F}}{\mathbf{=}}{\mathbf{m}}{\mathbf{a}}}$

We'll also use the Kinematic equation:

$\overline{){\mathbf{\u2206}}{\mathbf{x}}{\mathbf{=}}{{\mathbf{v}}}_{{\mathbf{0}}}{\mathbf{t}}{\mathbf{+}}\frac{\mathbf{1}}{\mathbf{2}}{\mathbf{a}}{{\mathbf{t}}}^{{\mathbf{2}}}}$

**a.**

Using Newton's second law equation:

F - f = ma

A 30.0 kg- box is being pulled across a carpeted floor by a horizontal force of 230 N, against a friction force of 210 N .

a. What is the acceleration of the box?

b. How far would the box move in 3 s, if it starts from rest?
