    Correct answer: W = 1,584,660 J = 1.58466 · 10⁶ J = 1.58466 MJ

    Explanation:

    Work is a measure of the change in potential energy in this case and the formula is W = Ep = m· g · h if we take g = 9.8 m/s²

    W = 77 · 9.8 · 2,100 = 1,584,660 J = 1.58466 · 10⁶ J = 1.58466 MJ

    God is with you!
