Question

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

Answer 1

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

Avg. Force = M*(average acceleration)

Answer 2

Typically a bullet leaves a standard 45 caliber pistol (5.0 inch barrel) at a speed of 262 m/s. If it takes 1 ms to traverse the barrel, determine the average acceleration by the 16.2 g bullet within the gun and then compute the average force Exerted on it
