Answer to Question #69593 in Physics for Lia

Question #69593
Q1. In 1865, Jules Verne proposed sending men to the Moon by firing a space capsule from a 220 metre long cannon with a final velocity of 10.97 km/s.
What would be the initial velocity of the capsule, vi in metres per second?

Q2.The acceleration in Jules Verne's capsule would have been monstrous.
Acceleration, a equal fraction numerator v subscript f minus v subscript i over denominator t end fraction , but we need to know how long the capsule is in the cannon, t.
We know the length of the cannon, so we could find out time by dividing the length by the average velocity of the capsule
What is the average velocity of the capsule, v with bar on top equal fraction numerator v subscript f plus v subscript i over denominator 2 end fraction in m/s?
