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

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