The barrel of a rifle has a length of 0.976 m. A
bullet leaves the muzzle of a rifle with a speed
of 561 m/s.
What is the acceleration of the bullet while
in the barrel? A bullet in a rifle barrel does
not have constant acceleration, but constant
acceleration is to be assumed for this problem.
Answer in units of m/s
