An electron in a cathode-ray tube is traveling horizontally at 2.10 x 109 cm/s when deflection plates give it an upward acceleration of 6.39 x 1017 cm/s2
How long does it take for the electron to travel 6.20 m?
What is the vertical displacement?

I got the time to be 2.95*10^-9, but I don't understand how to get the vertical displacement.
