Question

A chair of mass 16.4 kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force of 69.8 N that is directed at an angle of 21.5 degrees below the horizontal and the chair slides along the floor. Calculate the normal force that the floor exerts on the chair.
