A chair of weight 120 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of FFF = 42.0 N directed at an angle of 35.0 ∘ below the horizontal and the chair slides along the floor. Using Newton's laws, calculate n, the magnitude of the normal force that the floor exerts on the chair.
