Answer:

The answer to your question is the letter C. three times as much

Explanation:

Data

First step = 6 m

Second step = 18 m

Potential energy is the energy stored that depends on its position.

Formula

Pe = mgh

m = mass; g = gravity; h = height

Potential energy of the first step

        Pe1 = 6mg

Potential energy of the second step

        Pe2 = 18mg

-Divide the Pe2 by the Pe1

        Pe2/Pe1 = 18mg/6mg

                       = 3
