Homework Help: Calculus

Posted by Anonymous on Thursday, February 3, 2011 at 4:10pm.

ccording to Richard Graham in "SR-71 Revealed: The Inside Story", the Lockheed SR-71 Reconnaissance plane accelerates from a standing start to a speed of Mach 3 (3 times the speed of sound) "in about 14 minutes". (During that time it also climbs to an altitude of about 70,000 feet, so the acceleration is not as impressive as you might otherwise expect.) Assuming that the time is exactly 14 minutes, and the speed of sound is 1100 feet per second, this is an average acceleration of ? feet per second squared. Assuming that the acceleration is constant, during that time your SR-71 covers a distance of ? miles.
