    Physic Brahs, need help for reps.

    Need the misc's help for this physics question, serious.

    1. A box of books weighing 325N moves at a constant velocity across the floor when the box is pushed with a force of 425N exerted downward at an angle of 35.2 degrees below the horizontal. Find mu sub k between the box and the floor.

    Normal Force = Fn = 325 N
    Applied Force = 425 N
    X is horizontal axis
    Y is Vertical Axis
    Projected applied Forces:
    Fx = 425 cos(35.2)
    Fy = 425 sin(35.2)

    Frictional Force = Fk = (Fy+Fn)*uK
    Const Velocity when Fk = Fx

    ie: Fx = (Fy+Fn)*uk
    uk = Fx/(Fy+Fn)
    uk = 425cos(35.2)/(425sin(35.2)+325)
    uk = .6093
