Best ResponseYou've already chosen the best response.0Given : 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

Best ResponseYou've already chosen the best response.0That is a similar problem I found. Put in your data and see if it works.

Best ResponseYou've already chosen the best response.0I don't know. Try it and see. Why don't you google the problem. You could probably find the exact problem.
