Question
An electron is accelerated by a constant electric field of magnitude 325 N/C.
(a) Find the acceleration of the electron. (m/s^2)
(b) Use the equations of motion with constant acceleration to find the electron's speed after 1.05 10-8 s, assuming it starts from rest. (m/s)

m•a=e•E,
a = e•E/m = 1.6•10^-19•325/9.1•10^-31 = …
v = a•t = ...
