a gardener pushes a mower a distance of 900m in mowing a yard. the handle of the mower makes an angle of 40.0 degrees with the ground. the gardener exerts a force of 35.0 N alonf the handle of the mower. how much work does the gardener do in mowing the lawn?
Fp = 35*cos40 = 26.8 N. = Force parallel to yard.
Work = Fp*d = 26.8 * 900 = 24,130 Joules
