Dad (M = 84kg) is pushing his son (m = 14kg) in a box (negligible mass) across the living room rug at a constant velocity. He is pushing on the box with a force of 200N directed at 37° below the horizontal. The normal force exerted by the rug on the box is CLOSEST to?
N = mg+Fsinα = 14•9.8 +200•sin37
