Question #69594

Q1. The length of the cannon is 220 metres.

italic capital delta x equal v with bar on top t comma space s o space t equal fraction numerator italic capital delta x over denominator v with bar on top end fraction

Given your calculated average velocity, what is the amount of time in seconds that the capsule travels down the cannon?

Q2.Now that we know the time that the capsule would travel along the cannon barrel, we can calculate acceleration.

The barrel is 220m long, the final velocity is 10 970 m/s and you have calculated a value for time.

Use one of the methods from the week 2 lecture to give an acceleration in metres per second per second.
