Question

Which of the following has the largest gravitational potential energy

A. a 10kg dog running down the street at 30mph
B. a tightrope walker slowly crossing niagara falls
C. a 0.02kg bullet moving down the barrel at 800mph
D. a semi truck parked in a parking lot

Answer 1

Gravitational potential energy = mgh

Thus it is clear the higher the mass and height, the more will be the gravitational potential energy

Thus option B is the correct answer
