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

110000000 m/s²

Explanation:

From Newton's equation of motion,

v² = u²+2as Equation 1

Where v = final velocity of the space capsule, u = initial velocity of the space capsule, a = acceleration of the space traveler, s = length of the cannon.

make a the subject of the equation,

a = (v²-u²)/2s Equation 2

Given: v = 220 km/s = 220000 m/s. u = 0 m/s (As the space capsule was initially at rest), s = 220 m.

Substitute into equation 2

a = (220000²-0)/(2×220)

a = 48400000000/440

a = 110000000 m/s²

Hence the unrealistic large acceleration = 110000000 m/s²

the answer is c.)
