Find the speed of the electrons when they hit the screen

Reference no: EM13700392

Question: In a cathode ray tube in an old TV, electrons are accelerated from rest with a constant acceleration of magnitude 7.62 x 10¹³ m/s² during the first 1.93 cm of the tube's length; then they move at essentially constant velocity another 43.8 cm before hitting the screen.

Part A: Find the speed of the electrons when they hit the screen.

Please explain how you came to your conclusion.
