I would like to write vector expressions and determine the andle the slipe makes with the horizontal for the following.

a 2kg block is on a slope and is about to slip down, the coefficient of static friction is 0.4.

so far I have

W=2g
F=Fi
N=Nj

and tan-1 0.4 = 21.8 degrees.

W=2g (g=9.8)
N=Nj
F=0.4Ni

and W+N+F=0

Am I on the right track?

Sorry its angle and slope not andle and slipe...
