Please help on the last question. Most likely it's something simple, but I just can't see it. Thanks.
(a) What is the magnitude of the acceleration of an electron in a uniform electric field of 4.20 106 N/C?
a= 0.73x10^18 m/s2 (Correct)
(b) How long would it take for the electron, starting from rest, to attain one-tenth the speed of light?
t= 0.40x10^-10 s (Correct)
(c) How far would it travel in that time?
I applied d=at^2/2, with the above values for a and t, but it is not correct.
Thanks.
