Aproton traveling with velocity 3.60 x 10^4 m/s enters a region of space where there is an electric field e = -5.0 x 10^5 n/c. (a) what is the proton's acceleration?
(b) after it enters the electric field, how much time passes before the proton comes to rest?
(c) how far does it travel in the field before coming to rest?
