## Homework Statement

A proton is traveling with a speed of v = 2.990x10

^{8}m/s. Calculate the (relativistically correct) value of the kinetic energy for this proton. Assume that the speed of light is c = 3.000 x 10

^{8}m/s and that the mass of the proton is 1.673 x 10

^{-27}kg.

Note: Do your calculations to 4 significant figures. Then round off to give an answer good to 3 significant figures. Be sure to include the correct abbreviation for the SI unit.

## Homework Equations

K = 1/2 mv

^{2}

Limit is K = 1/2mC

^{2}

## The Attempt at a Solution

K=1/2(1.673x10

^{-27})(2.990x10

^{8})

K=2.50x10

^{-19}J

Is this correct? I feel like I'm missing something here...
