# In 1865 Jules Verne proposed sending men to the Moon by firing a space capsule from a 220-m-long cannon with final speed of 10.97 km/s. What would have been the unrealistically large acceleration experienced by the space travelers during their launch? (A human can stand an acceleration of 15g for a short time.) Compare your answer with the free-fall acceleration, 9.80 m/s2.

To determine
The acceleration experienced by the space traveller.

Explanation

Given Info:

The initial velocity of the space traveller is 0

The final velocity of the space traveller is 10.97â€‰km/s

The displacement of the space traveller is 220â€‰m

Explanation:

The formula used to calculate the acceleration of the space traveller is,

a=v2âˆ’v022Î”x

• Î”x is the displacement of the space traveller
• v is the final velocity of the space traveller
• v0 is the initial velocity of the space traveller
• a is the acceleration

Substitute 0 for v0 , 10.97â€‰km/s for vf and 220â€‰m for Î”x to find a .

a=((10
