Junes Verne in 1865 suggested sending people to the Moon by firing a space capsule from a 245 m long cannon with a launch speed of 10.37 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during launch?

Use the equation v² = u² + 2as.
u is initial velocity (in this case 0)
v is final velocity (1037000 m/s)
s is distance (245 m)
a is the acceleration you are trying to find.
It is important to express v in m/s since you are measuring the distance in metres. It is also helpful if you want to say that it is the equivalent of so-many "g's" (1g = gravitational force = 9.8 m/s²).

218.7442315 km/s/s
I use MS Excel and the goal seek function
I also know that distance = 1/2*A*T
I also know that velocity = A*T
