A person pushes a 11.0 kg lawn mower at constant speed with a force of 82.0 N directed along the handle, which is at an angle of θ = 45.0° to the horizontal.Calculate the normal force exerted vertically upward on the mower by the ground.

well, the normal force has to overcome the weight of the mower, mg, plus the downward force of pushing, which is 82Cos45.
