An early proposal for space travel involved putting astronauts into a large artillery shell and shooting the shell from a large cannon. Assume that the length of the cannon is 30. m and that the velocity needed by the shell to achieve orbit is 15,000 m/s. If the acceleration of the shell is constant and takes place only within the cannon, what is the acceleration of the shell in gees?
