A jet fighter pilot wishes to accelerate from rest at a constant acceleration of 4g* to reach Mach 2 (three times speed of sound) as quickly as possible. Experimental tests reveal that he will black out if this acceleration lasts for more than 5.0 s. Use 331 m/s for the speed of sound. a) Will the period of acceleration last long enough to cause him black out? b) What is the gretest speed he can reach with an acceleration of 5g before black out? * Note: 5g means 5 times the acceleration of gravity
