In 1865, Jules Verne suggested sending people to the Moon by launching a space capsule with a 207.9 m long cannon. The final speed of the capsule must reach 11.31 km/s. What acceleration would the passengers experience?
The average speeed in the cannon is Vav = V/2 (where V is the exit velocity), and the time the capsule takes to leave the barrel is t = L/Vav = 2L/V
The acceleration rate a is V/t =
a = V^2/(2L)
