A chair of mass 14.0kg is sitting on the horizontal floor; the floor is not frictionless. You push on the chair with a force F = 40.0N that is directed at an angle of 43.0∘ below the horizontal and the chair slides along the floor.

Answer 1

M*g = 14 * 9.8 = 137.2 N. = Wt. of chair.

Fn = Mg + F*sin43 = 137.2 + 40*sin43 =
164.5 N. = Normal force.
