  1. Fb = 10kg * 9.8N/kg = 98N.

    Fb =98N @ 0 deg.

    Fp = 98sin(0) = 0 = Force parallel to plane(hor).

    Fv=98cos(0) = 98N.=Force perpendicular to the plane.

    a. Fn = Fap - Fp - Ff = 0,
    25 - 0 - Ff = 0,
    Ff = 25N = Force of friction.

    b. Ff = uFv = 25,
    u*98 = 25,
    u = 0.26 = Coefficient of friction.
