Junes Verne in 1865 suggested sending people to the Moon by firing a space capsule from a 195 m long cannon with a launch speed of 12.78 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during launch?

____ m/s^2

• Physics -

It is the acceleration a that you get by requiring that V^2 = 2 a X

V is the launch vecloity and X = 195 m
