A potted plant sits on the shelf of a flower store where it has
150 J of a gravitational potential energy relative to the floor.
If the
the plant is 2.5 m above the floor, what is the mass of the
plant?

Answers & Comments
Answer:
Using the formula for the finding the gravitational potential energy GPE
GPE= mgh
where
GPE= 150J
m=mass= unknown
g= acceleration due to gravity= 9.80m/s^2
h= height= 2,5m
solving the above formula for m gives
m= GPE/gh= 150/9.80*2.5= 6.1kg
