Please help on the last question. Most likely it's something simple, but I just can't see it. Thanks.(adsbygoogle = window.adsbygoogle || []).push({});

(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.
