## Homework Statement

at what speed does the expression for relativistic kinetic energy vary from the non-relativistic expression by 5%?

## Homework Equations

Relativistic kinetic energy K=(gamma-1)mc^2

Non-relativistic kinetic energy K=0.5mv^2

## The Attempt at a Solution

I'm not sure how to attempt this!

Should I be finding the difference? ie K(relativistic)-K(non-relativistic)=0.05??
