Yep I used special relativity, because my teacher keeps emphasising that we should be doing "complicated" calculations. Now I'll have to see if my teacher likes what I've done :)

Ok- I did so, and got roughly 2.4*10^7 m/s, which gave a Lorentz factor of 1.003 So I'll have a go with the relativistic equation now... Does 1.003 represent that there is a dilation of 3%? I'm just trying to figure out how to explain that calculation, and the internet generally describes the...

@J Hann Wait a sec- shouldn't I just use E= m(r)*c^2 - m0*c^2 ? Or is your equation derived from that?

@J Hann thanks- I'll re-calculate it with that- we only ever learned relativistic mass, length and time in class so I assumed there weren't other equations (whoops) @ehild I applied the multiplication rule... log (a) + log (b) = log (a*b) But thanks for recommending the Lorentz factor- the more...

Homework Statement So I'm trying to find the final velocity of a proton that is being accelerated by a particle accelerator, just before it collides with a particle. All I have is its kinetic energy just before collision: 4.7066×10^(-13) J. I thought I should use KE = 1/2 mv^2 but then...
