## Homework Statement

A wounded soldier caught in Line of fire is pulled away by his comrade with a force of 70lbs at 65 degrees. The wounded solider(with his gear) weighs 180 lbs and the coefficient of friction between him and ground is .55

How quickly will he be accelerated out of harms way?

## Homework Equations

u=coefficent of friction

f=uF, w=mg, F-f=ma

## The Attempt at a Solution

f=uFn

f=(.55)(180-64.44lbs)

f=64.108lbs

w=mg

180=m(32.2)

5.59kg=mass

I don't know what to do(correctly) after this. Have I done anything wrong in the steps shown above?
