## Homework Statement

A 2 kg object is placed on a plane inclined at an angle of 30 degrees. If the coefficient of static friction is 1, and the coefficient of kinetic friction is 0.1, what is the net force on the block?

## Homework Equations

F = ma

## The Attempt at a Solution

I made a FBD with a force table of the following: F

_{n}, w, and F

_{f}. My acceleration along the x is -4.1 m/s

^{2}and F

_{n}= +17.3 N.

My confusion is the question of the sum of the forces. If I add up all the forces along the x and the y, I get a net sum of -25.6 N. The correct answer is 2.7N. Help please!
