A gardener pushes a lawn mower a distance of 1500 m mowing a yard. The handle of the mower makes an angle of 30° with the ground. The gardener exerts a force of 30.0 N along the handle of the mower (that is, at the 30° angle with respect to the ground). How much work does the gardener do mowing the lawn?
