In a cathode ray tube in an old TV, electrons are accelerated from rest with a constant acceleration of magnitude 7.03x1013 m/s2 during the first 2.0cm of the tube's length; then they move at essentially constant velocity another 45 cm before hitting the screen.
a) find the speed of the electron when they hit the screen.
b) how long does it take them to travel the length of the tube?
