What is the bullet's acceleration?

Question

A force of 1.9 N is exerted on a 5.7 g rifle bullet. What is the bullet's acceleration?
___ m/s²

Answer 1

Force = mass x acceleration  -- F = ma

 

But make sure the units are correct.  Newtons and meters go with kilograms, so the mass of the bullet has to be converted from from 5.7 g to .0057 kg.

 

So now we can figure it out...

 

1.9 N = .0057 * a

1.9 / .0057 = a

333.3 m/s² = a

 

So the acceleration is 333.3 m/s²
