Answer:

Ep = 3704.4 J

Explanation:

Data:

  • Mass (m) = 126 kg
  • Gravity (g) = 9.8 m/s²
  • Height (h) = 3 m
  • Potential Energy (Ep) = ?

Use formula:

  • Ep = m * g * h

Replace:

  • Ep = 126 kg * 9.8 m/s² * 3 m

Multiply, but it tells us that the units should not be used in the answer, so we solve it as follows:

  • Ep = 3704.4

What is the GPE?

The GPE is 3704.4 Joules.
