A bullet leaves the barrel of a rifle with a speed of 300m/s. If the length of the barrel is 0.9m, at what rate is the bullet accelerated while in the barrel?

Your school SUBJECT is probably PHYSICS.
We can use the formula:
vf^2 - vo^2 = 2ad
where
vf = final velocity
vo = initial velocity
a = acceleration
d = distance
Substituting,
300^2 - 0^2 = 2(a)(0.9)
a = ?
Now solve for a. Units in m/s^2
