In an electric tube, an electron of mass 9.1*10 to the power of negative 31 kg experiences a net force of magnitude of 8.0*10 to the power of 15 over a distance of 2.0cm.
A)calculate the magnitude of the electron's acccleration
B)assuming it started from rest, how fast would the electron be moving at the end of 2.0cm motion.
The Attempt at a Solution
m=9.1*10 to the power of negative 31
=8.0*10 to the power of 15/.1*10 to the power of negative 31 kg
I didnt get how to question B)
