A helicopter is delivering food in an emergency situation, where it is difficult to
land. The engineer is tasked with determining what heights the package could be
dropped without breaking. She knows that if the package strikes the ground
faster than the critical speed of 64.Omph, then the package will break. Neglect
drag.
At what height would the package hit the ground with the critical speed (in given
units)?
