Question

if the roller coaster is 127 meters tall and has 622,300 J of potential energy how much does it weigh/ what is the mass?

Answer 1

500 kg

Step-by-step explanation:

using the formula Potential energy (p.e)=mgh where g= acceleration due to gravity whose value is 9.8

so,pe =mgh

622300=m*9.8*127

m=500kg
