typically a bullet leaves a standard 45 caliber pistol at 262 m/s. if it takes i millisecond to transverse the barrel, determine the average acceleration experienced by the 16.2 gram bullet within the gun's barrel and then compute the average force exerted on it

Vfinal = sqrt(2aX)
X = barrel length
Solve for average acceleration, a.
Avg. Force = M*(average acceleration)
