  1. Gravitational energy (in joules)
    = mgh
    where
    m=mass (k)
    g=acceleration due to gravity (m/s²)
    h=height (m)
    Solve for h.

  2. We use the formula
    PE = mgh
    where
    PE = potential energy (J)
    m = mass (kg)
    g = acceleration due to gravity = 9.8 m/s^2
    h = height (m)

    Substituting,
    1970 = 82(9.8)(h)
    h = 2.45 m

    hope this helps~ `u`
