A person pushes a 22 kg lawn mower at a constant speed with a force of 91 N directed along the handle, which is 63° above the horizontal,
as shown.
a) Draw the force diagram of the lawn mower.
b) Determine the horizontal resistive force on the lawn mower.
c) Determine the normal force from the ground
