Older televisins display a picture using a device called a cathode ray tube, where electrons are emitted at high speed and collide with a phosphorescent surface, causing light to be emitted. The paths of the electrons are altered by magnetic fields. Consider one such electron that is emitted with an initial velocity of 1.85 x 107 m/s in the horizontal direction when magnetic forces deflect the electron with a vertically upward acceleration of 5.40 1015 m/ 2. The phosphorescent screen is a horizontal distance of 9 cm away from the point where the electron is emitted. (a) How much time does the electron take to travel from the emission point to the screen? ______s (b) How far does the electron travel vertically before it hits the screen? ______cm
