A 110 N force, directed at an angle θ above a horizontal floor, is applied to a 24.0 kg chair sitting on the floor. If θ = 0°, what are (a) the horizontal component Fh of the applied force and (b) the magnitude FN of the normal force of the floor on the chair? If θ = 31.0°, what are (c)Fh and (d)FN? If θ = 55.0°, what are (e)Fh and (f)FN? Now assume that the coefficient of static friction...
