Question: How fast ( to three significant figures ) would a bullet of mass m = 0 . 0 0 4 2 kg need to move

How fast (to three significant figures) would a bullet of mass
m =0.0042 kg need to move in order to equal the linear momentum p
of the container ship?
As you would suppose, the bullet would need to travel very fast. The velocity would be so large, in fact, that it could be compared to the velocity of light in vacuum, or
c =3.00E+8 m/s. As a result, the relativistic effect in linear momentum is significant, so a correction is needed, given by p=\gamma mv, with \gamma =1(pmc2).2Use these tools to find the velocity v.
