In his novel From the Earth to the Moon (1865), JulesVerne describes a spaceship that is blasted out of a cannon, calledthe Columbiad, with a speed of 12,000 yards>s. The Columbiad is900 ft long, but part of it is packed with explosives, so the spaceship accelerates over a distance of only 700 ft. Estimate the acceleration experienced by the occupants of the spaceship duringlaunch. Give your answer in m>s2. (Verne realized that the “travelers would . . . encounter a violent recoil,” but he probably didn’tknow that people generally lose consciousness if they experienceaccelerations greater than about 7g ∙ 70 m>s2.)
