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?
