Which object would have the most potential energy?

PE = mgh

g = 9.8 m/s2

a
a 10 kg dog sitting on the ground
b
a 2 kg bottle of soda on a shelf 2.5 meters tall
c
a 0.25 kg book sitting on a table 2 meters tall
d
a 5 kg bowling ball in a person's hand at 0.75 meter

b. The 2 kg bottle of soda on a shelf 2.5 meters tall would have the most potential energy, calculated as PE = (2 kg)(9.8 m/s2)(2.5 m) = 49 J.
