1. The problem statement, all variables and given/known data

A 5.1 g bullet leaves the muzzle of a riﬂe with
a speed of 467 m/s.
What constant force is exerted on the bullet
while it is traveling down the 0.5 m length of
the barrel of the riﬂe?

2. Relevant equations
V2=Vo2+2a(x-xo)
F=ma

3. The attempt at a solution
4672=2a(.5-0)
a=218089

F=.051*218089
F= 1112.2539
