A bullet accelerates the length of the barrel of a gun, which is 0.75 at a rate of 250m/s^2. How long is the bullet inside the gun's barrel? What is the velocity of the bullet when it leaves the gun? Given the muzzels velocity, how long does it take the bullet to hit a target 250m away, assuming no air resistance?
