Thank you. I went outside for a break and had the revelation. I feel stupid now. I got the answer for each part now. I don't know why I wasn't thinking about looking up the charge and mass. Thanks again!

a) Find the magnitude of the acceleration of the proton.
b) How long does it take the proton to reach this speed?
c) How far has it moved in that...
