1. An electron accelerates from rest through a potential difference of 182 V.
What is its final speed?
_____ m/s
2. An electron that has a horizontal initial speed of 4.50 x 10^6 m/s enters a region that has an electric field of 120 V/m pointing vertically upward.
(a) How long does the electron take to travel 9 cm in the horizontal direction?
_____ s
(b) In this same time, what is the vertical displacement of the electron? Treat up as positive.
_____ cm
