A man pushes a lawn mower with a force of 25 newtons. The lawn mower has a mass of 17 kilograms and the handle makes an angle of 60 degrees with the horizontal. How much work is done if the lawn mower is pushed a total of 500 meters

Answer:

6250 J

Explanation:

Work is the distance times the component of the force along that distance.

The horizontal component of the force is:

25 N × cos(60°) = 12.5 N

So the work done is:

W = (500 m) (12.5 N)

W = 6250 J
