A chair of weight 115 N lies atop a horizontal floor; the floor is not frictionless. You push on the chair with a force of F = 38.0 N directed at an angle of 43.0^\circ 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.

    The normal force must oppose all forces in the vertical direction because the chair doesn't move into the floor! \[0 = mg - F \sin(\theta)\]
