A bullet is fired out of a gun at 400 m/s. If the barrel of the gun is 0.800 m long, what is the acceleration of the bullet as it moves from rest to the end of the barrel. Is there a way to solve this using calculus?

the question is similar to an object starting move from rest to 400m/s for a distance of 0.8m. Use \(v^2 = u^2 + 2as\)

are you telling me that the final velocity will be 400 m/s?

And the initial velocity, 0?
