In a television tube, electrons initially at rest are accelerated by a uniform electric field of magnitude 4.0 times 10⁵ N/C during the first 5.0 cm 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 electrons when they hit the screen.

(b) How long does it take them to travel the length of the tube?
