A proton accelerates from rest in a uniform electric field of650 N/C. At some time later, its speed is1.40 x 106 m/s.
(a) What is the magnitude of the acceleration of the proton?
1 m/s2
(b) How long does it take the proton to reach this speed?
2 s
(c) How far has it moved in this time interval?
3 m
(d) What is its kinetic energy at the later time?
4 J
