A chair of mass 16.0 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 43.0 N that is directed at an angle of 42.0 ∘ below the horizontal and the chair slides along the floor. Use Newton's laws to calculate the normal force that the floor exerts on the chair.
