A chair of mass 10.0 kg is sitting on the horizontal floor; the floor is frictionless. You pull on the chair with a force F = 30.0 N that is directed at an angle of 37.00 above the horizontal, and the chair slides along the floor. a. Draw a clearly labeled free-body diagram for the chair b. Use your diagram and Newton's laws to calculate the normal force that the floor exerts on the chair
