## Homework Statement

You drag a suitcase of mass 17 kg with a

force of F at an angle 40.6◦ with respect to

the horizontal along a surface with kinetic

coefficient of friction 0.59.

The acceleration of gravity is 9.8 m/s2 .

If the suitcase is moving with constant ve-

locity 2.68 m/s, what is F?

Answer in units of N.

## Homework Equations

Ff = miuFn

All forces equal

## The Attempt at a Solution

so first i broke it into components,

Ff = Fcostheta

Fn + Fsin theta = Fg

Ff = miuFn = miu( Fg - Fsin theta)

miu ( Fg - Fsin theta) = Fcos theta

i got up to here and idk how to solve it
