Ella has a mass of 56 kg, and Tyrone has a mass of 68 kg. Ella is standing at the top of a skateboard ramp that is 1.5 meters tall.

Which conclusion is best supported by the given information?

A. If Tyrone stands at the top of the same ramp, his potential energy will be less than Ella's.

B. If Tyrone stands at the top of a 1 m high ramp, his potential energy will be greater than Ella's.

C. If Tyrone stands at the top of the same ramp, his potential energy will be the same as Ella's.

D. If Tyrone stands at the top of a 2 m high ramp, his potential energy will be greater than Ella's.

Jacob Sloan · Answer 1

Correct answer is D.

The potential energy is equal to m·g·h: mass · 9'8 · height

A and C are automatically wrong, since at the same height, the higher mass means higher potencial energy. At 1m, the energy of Tyron won't be as high as Ella's. And at higher altitude than Ella, no doubt a higher mass will have higher energy.
