mass of coaster is 800kg
second hill is 70m
do you take 800*70*9.8=548800

• physics -

Yes. use units, here it will be energy in Joules

• physics -

Could you show me how my answer would look please, and would you happen to know aside from the mass what other measurement (numerical value) need to know to calculate GPE?
