A proton accelerates from rest in a uniform electric field of660 N/C. At one later moment,its speed is 1.40 Mm/s(nonrelativistic because v is much less than the speed oflight).
(a) Find the acceleration of the proton.
m/s2
(b) Over what time interval does the proton reach this speed?
s
(c) How far does it move in this time interval?
m
(d) What is its kinetic energy at the end of this interval?
J
