Josh is cutting the grass with a push mower across horizontal ground! He pushes with a force of 52 N to the left, but downwards at an angle of 40º below the horizontal. There is a small
coefficient of friction of 0.20. The mower has a mass of 8.4 kg. Determine the force of friction
and the acceleration on the mower.
