A proton accelerates from rest in a uniform electric field of 662 N/C. At some later time, its speed is 1.50 x 106 m/s.
(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 interval?
(d) What is its kinetic energy at the later time?
