Object a has a gravitational potential energy of 24 joules when it rests on a shelf 5 m above the ground. object b has a mass that is three times the mass of object a. what would be the gravitational potential energy of object b when it rests on a shelf 10 m above the ground?

GPE=mgh
m=mass
g=acceleration due to gravity
h=height above the ground

24=mg(5m)

we want to find when we have
3mg(10m)
we can manipulate it into the other form like this
3mg(2)(5m)
(3)(2)mg(5m)
5(mg(5m))
so it is going to be 5 times the potentail energy

24*5=120
answer is object B has a potential energy of 120 joules

another way is to to solve for m but that's too hard (sarcastic)
24=mg(5m)
solve for m
(24)/(g5m)=m
multiply by 3 to get the mass of object B
72/(g5m)=3m

subsitute
object b potentail energy is 3m g times 10
3m times g times 10 is equal to
(72/(g5m))g(10m)=
720/5=
120

answer is 120 joules
