Answer

He would have to transfer $~~3.0\times 10^5~J~~$ of energy.

Work Step by Step

We can estimate that Daniel Goodwin's mass was $70~kg$ We can find the change in gravitational potential energy from the bottom of the building to the top: $\Delta U = mg~\Delta h$ $\Delta U = (70~kg)(9.8~m/s^2)(443~m)$ $\Delta U = 3.0\times 10^5~J$ He would have to transfer $~~3.0\times 10^5~J~~$ of energy. Note that the amount of energy transfer required is the same for both cases.
