A crate of potatoes of mass 9.0 kg is on a ramp with angle of incline 30° to the horizontal. The coefficients of friction are μs = 0.69 and μk = 0.41. Find the frictional force (magnitude and direction) on the crate if the crate is at rest.
magnitude N?



    friction up the plane: mg*mu*cosTheta


    DO i use uk or us for u cuz i used both n it was wrong

    I put 9(9.8)x9(.69)(.41)cos(30) :/


    please help me i am stuck
