- Homework Statement:
- Hi! So for my a levels I’ve been doing practice papers and I’m stuck. I have to calculate the kinetic energy of a proton after acceleration except I’m only given the charge of +1.6x10^-19 , a potential difference of 80kV, and a mass of 1.7x10^-27kg

- Relevant Equations:
- Kinetic energy = 1/2 x mass x velocity^2

So first I tried to use KE=1/2 x m x v^2 but then realized I didn’t have the velocity and I can’t figure out a way to obtain it. I then tried to work out the energy using a different equation, W= q x v but that left me with 1.28x10^-14 J which seemed too small.

I also then have to calculate the maximum speed of the proton which I’m confused at how to do if I don’t have the velocity.

Thanks in advance!
