Jules Verne proposed sending men to the Moon by firing aspace capsule from a 220

Question

Jules Verne proposed sending men to the Moon by firing aspace capsule from a 220 m long cannon with final speed of 10.97km/s.

(a) What would have been the unrealistically large accelerationexperienced by the space travelers during their launch? (A humancan stand an acceleration of 15g for a short time.)
1

(b) Compare your answer with the free-fall acceleration, 9.80m/s2 (i.e. how many times stronger than gravity is thisforce).

Explanation / Answer

Vf2 / 2d = a [10.97(1000)] 2 / (2 * 220) = 273502.0455m/s2 (b) divide the acceleration by gravity (9.8) tofind it in terms of "g's" 273502.0455/9.8 = 27908.37g Therefore it is 27908.37 times faster acceleration thangravity
