What is the gravitational potential energy of the tennis ball at the top of each hill?
(mass of a tennis ball is approximately .057 kg) Hint: Remember to convert centimeters to meters.

Ok so I had to make a roller coaster....long story, but its made out of cardboard. The heights of each hill is:
The first one : 49 cm
The second one : 32 cm

Thanks to all who answer.
