Then, can F=ma be F_e=ma?
Does it matter if I use F_e=ma then use v_f²=v_i²+2ad to find a velocity or I use Δ(PE)=qEd then KE=.5mv² to find the velocity?

(I'm given the field E, q, initial velocity, the distance moved, and the mass, and asked to find the final velocity.)
(For some reason solving using the two different methods gave me two different answers. I don't know if I made a calculation mistake or a problem solving mistake)
