Two Dimensional Kinematics

  1. Jul 9, 2009 #1
    1. The problem statement, all variables and given/known data

    An electron in a cathode-ray tube is traveling horizontally at 2.60×109 cm/s when deflection plates give it an upward acceleration of 5.90×1017 cm/s^2.What is its vertical displacement during this time?

    2. Relevant equations



    3. The attempt at a solution
    I got this one but other than that I am so lost How long does it take for the electron to cover a horizontal distance of 6.10 cm? t =2.35×10^-9s

    Where did the 6.10 cm come from?

    It was given to me in the original problem.

    Wait, I'm confused. I don't see it in the problem you posted.

    In fact, the problem as you posted it is incomplete. It talks about "vertical displacement during this time" but there's no time given. Why don't you post the problem again but make sure to include the whole thing this time :wink:

    Oops...I am sorry about that.

    Isn't that the same thing you posted before, though?

    Sorry to not be helpful, but I'm really confused by what you're posting.
