A force of 5 newtons acting through a distance of 10 meters does (5 x 10) = 50 joules of work.
The weight of the cart and the slope of the surface are not required and are of no interest.
This is tough, because she's probably not pushing exactly parallel to the ground. Part of
her force is pointing straight down at the ground, while another part of the force pushes
horizontally. Only the horizontal 'component' does work; it's less than 20N.
But ... we don't know the height of the handles above ground, or how tall Amy is, or what the
angle is between the handle and the ground ... any of the stuff that would help us calculate
how much of the 20N actually moves the mower. So we have to just assume that she's
pushing horizontally with the whole 20N.
Then the work is [ (force) times (distance) ] = (20 x 10) = 200 newton-meters.
"20 newtons" is not work at all. It's force, equivalent to about 4.5 pounds.
Work = Force x distance
So,
W = 20 N x 10 m
= 200 J
a Newton Meter is a Joule
Work = force x distance = 20N x 10m = 200N•m
W=Fd
20N*10m=200N*m

Figure about 3 pounds per horsepower. Double that if the motor is more than 30 years old (cast iron block).
Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.Work is equal to force x distance. If the force is specified in Newtons, and the distance in meters, then the work is in Joules.
The application of 75N of force through a distance of 8 meters results in 600 newton-meters = 600 joules of work.

Work=Force+Distance =joule
Depends on the size of the mower.
this piece of **** doesn't work worth ####. I could wipe my ### with my questions and it would give me a better answer.
That will vary for each make and model of mower.
It depends on what kind of lawn mower (push or ride). I sell my fixed push mowers usually for $30.
give up and hire a lawn service...

about as much as a lawn mower
Check the oil/fuel mix and make sure you have it mixed to the correct ratio. Else, try raising the blade on the lawn mower. If you have the lawn mower blade too low, mowing tall grass, it can make too much work for the mower and will cause it to overheat.
