1. The problem statement, all variables and given/known data In a TV set, an electron beam moves with horizontal velocity of 2.5 x 107 across the cathode ray tube and strikes the screen, 40 cm away. The acceleration of gravity is 9.8 m/s2. How far does the electron beam fall while traversing this distance? Answer in units of m. 2. Relevant equations x = voxt vy = voy - gt 3. The attempt at a solution I solved for t: x = voxt .04 = 2.5 x 107 t = 1.6 x 10-9 Then I plugged t into vy = voy - gt. vy = 0 - (9.8)(1.6x10-9) vy = -1.568x10-8 Now I am not sure if I have the correct values plugged in because I do not think I am supposed to come up with a negative answer. I did draw a picture but am not sure if my math corresponds to the picture. Any suggestions are appreciated, Thanks.
