**1. The problem statement, all variables and given/known data**

You're using a rope to pull a sled at constant velocity across level snow,with coefficient of kinetic friction 0.050 between sled and the snow. The sled is loaded with physics books, giving a total mass of 19 {\rm kg}.

**2. Relevant equations**

F=\mu*n

**3. The attempt at a solution**

I tried solving for the force and the force of friction seperately then subtracting between them... Not sure if that's correct.

EDIT: I'm sorry I'm on the second part of this question which asks for the same force but at a slope of 30 degrees above horizontal.
