**what is the speed of the proton??**

## Homework Statement

What is the speed of a proton after being accelerated from rest through a 50x10

^{6}potential difference?

m_proton = 1.67x10

^{-27}kg

C = 1.6x10

^{-19}c

* This question is in Relativity.

## Homework Equations

Voltage(v) = Joule(j)/Columb(c)

K = 1/2(mu

^{2})

## The Attempt at a Solution

Firstly, i timed 1.6x10

^{-19}to 50x10

^{6}to find the Energy(j

). Then plugged into the kinetic energy formula to find u(speed_proton). But which is wrong. what is the mistake?
