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?

You are pushing a 50 kg lawn mower with a force of 80 N at an angle of 45 degreesfrom the ground (the force points at 45 degreesinto the ground, like how you’d expect when you are pushing a lawn mower). What are the A) horizontal and B) vertical component of this force? The ground is pushing straight upwards at the lawn mower with some amount of normal force. The grassy lawn is also exerting a friction force against the...
