The work done by the person is calculated as the force applied multiplied by the distance the cart moves in the direction of the force. In this case, the work done would be 40 newtons x 10 meters = 400 joules.
The wheelbarrow wasn't invented by a specific person. Rather, it was invented by the Greeks in Ancient Greece. It was invented in around 406 B.C.

When a wheelbarrow is used, the person pushing it supplies mechanical energy to overcome frictional forces and lift the load. Some of the person's chemical energy from metabolism is converted into kinetic energy to move the wheelbarrow, and potential energy when lifting the load.
A person weighing 150 pounds would be equal to 667.2 newtons.
The person pulling with 600 newtons of force would overpower the person pulling with 500 newtons of force. The resulting net force would be 100 newtons in the direction of the person with the higher force.
About 667 newtons per 150 pounds.
588.399 newtons. (60 * 9.80665)
A wheelbarrow represents a second-class lever because the load (the materials in the wheelbarrow) is positioned between the effort (the person pushing or pulling the wheelbarrow) and the fulcrum (the wheel). This lever configuration allows the user to lift heavier loads with less effort compared to a first-class lever.
F = M a a = F / M = (15) / (58) = 0.259 meters/sec2 (rounded) (about 2.6 percent of one 'G')
