2,088 J
2 Newton-meters
Potential energy = mg * h Given mg = 25 N and h = 3 m So required potential energy = 75 J

The idea here is to multiply the force by the distance.

The idea here is to multiply the force by the distance.
To get the weight (in Newton), multiply the mass by Earth's gravitation - about 9.8, in SI units.
PE=mgh(20 N)(.5 m) = (25 N)xx=0.4 m
PE=mgh (20 N)(.5 m) = (25 N)x x=0.4 m
Have the required medical exam and take the test results to DMV.
700 x 4 = 2,800 newton-meters = 2,800 joules
In this case, work is the product of force and distance. (This assumes that both are in the same direction, and that the force doesn't change.)
