In this case, we have to use the potential energy definition


U=m\cdot g\cdot h

Where U = 1,780 Joules, h = 15 meters, g = 10 m/s2. Let's replace these values and solve for m


\begin{gathered} 1,780J=m\cdot10m/s^2\cdot15m \\ 1,780J=m\cdot150m^2/s^2 \\ m=(1,780J)/(150m^2/s^2) \\ m\approx11.87\operatorname{kg} \end{gathered}

Hence, its mass is around 11.87 kilograms.
