Hi Richard;

work=(force)(distance)

work=(mass)(acceleration)(height)

You are presenting the value of 100 in terms of Newtons. This is the unit of force, not mass. I will proceed assuming this is 100 Newtons, not 100 kg...

work=(100 N)(5 m)

work=500 joules

The unit of joules is Newtons-meters

The unit of joules is kg m

^{2}/s^{2}The unit of Newtons is kg m/s

^{2}Potential energy is (mass)(acceleration due to gravity)(height). This is a nearly identical equation as above. I need more information before I can proceed.
