    f = [ (u)(m)(g) ] / [ cos(x) - (u)*sin(x) ]

    Given : Angle ( θ ) = 21o Mass ( m ) = 23 kg Static friction μs = 0.56 g = 9.8 m/s2 μs = F /N F = μs N where N = m g(cosθ + µ sinθ) F = μs mg(cosθ + µ sinθ) =------ N

    That is a similar problem I found. Put in your data and see if it works.

    even though it says kinetic friction and not static friction?

    I don't know. Try it and see. Why don't you google the problem. You could probably find the exact problem.

    First, it should read "19 deg ABOVE the horizontal."

    Can you calculate the force of kinetic friction, and tell in which direction the force of friction is applied?
