Question: An F-15 supersonic fighter aircraft is in a rapid climb. At the instant it passes through a standard altitude of 25,000 ft, its time rate of change of altitude is 500 ft/sec, which by definition is the rate-of-climb. Corresponding to this rate-of-climb at 25,000 ft is a time rate of change of ambient pressure.

Part A: Calculate this rate of change of pressure in units of pounds per square foot per second.
