  • Answer:

    21.31 meters

    Explanation:

    Since we're working with gravitational potential energy (GPE):

    GPE (Joules) = mass (kg) * gravity (m/s^2) * height (meters)

    1. Figure out what we have:

    GPE = mass * gravity * height

    We're looking for height, and we have the other three, so we're set to move on.

    2. Isolate the unknown variable (height):

    (GPE) / (mass * gravity) = height

    3. Plug in your numbers:

    (3.78 * 10^7 J) / ((1.81 * 10^5 kg) * (9.8 m/s^2)) = 21.31 meters
