#3/Q2 Must show work, all equations/methods used, and steps taken to derive at the final answer.

As most of you know, commercial transport planes cruise at an altitude of approximately 10,000 m (~33,000 ft). The power required to maintain level flight depends on air drag, or resistance at that altitude, which may be estimated by the following relationship, see attachment.

Power = 1/2p air C d AU cubed (see attachment, does not translate correctly).

represents the drag
