Jules Verne in 1865 suggested sending people to the Moon
by firing a space capsule from a 220-m-long cannon with a
launch speed of 10.97 km/s. What would have been the
unrealistically large acceleration experienced by the space
travelers during launch? Compare your answer with the
free-fall acceleration 9.80 m/s2.
