Answer

The decrease in gravitational potential energy each second is $~~-2.7\times 10^9~J$

Work Step by Step

We can find the change in gravitational potential energy each second: $\Delta U = mg~\Delta h$ $\Delta U = (5.5\times 10^6~kg)(9.8~m/s^2)(-50~m)$ $\Delta U = -2.7\times 10^9~J$ The decrease in gravitational potential energy each second is $~~-2.7\times 10^9~J$
