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?
o A. 72 joules
o B. 120 joules
o C. 144 joules
o D. 240 joules

ISn't GPE proportional to mass x height?
24 = w x 5
w = 24/5
w = 4.8
4.8 x 3
= 14.4
gpe = 14.4kg x 10m
= 144
w = 24/5
w = 4.8
4.8 x 3
= 14.4
gpe = 14.4kg x 10m
= 144
where does the 3 come from
144
