time to get to screen:
time=distance/velocity
how far does it fall?
d=1/2 g t^2
In a TV set, an electron beam moves with horizontal velocity of 2.5 × 107 m/s across the cathode ray tube and strikes the screen, 44 cm away.
The acceleration of gravity is 9.8 m/s2 .
How far does the electron beam fall while traversing this distance?
