Best ResponseYou've already chosen the best response.0\[\Delta y=\Delta y_1+\Delta y_2=\frac 12 a(\frac{L}{v_0})^2+L +D \] \[x_1=v_0t\] \[t=\frac{x_1}{v_0}=\frac{L}{v_0}\] \[\Delta y_1=v_0t+\frac 12 at^2\] \[\Delta y_1=v_0\frac{L}{v_0}+\frac 12 a(\frac{L}{v_0})^2\] \[\Delta y_1=\frac 12 a(\frac{L}{v_0})^2+L\] now outside o the acceleration plates \[x_2=v_0t\] \[t=\frac{x_2}{v_0} =\frac D{v_0}\] \[\Delta y_2=v_0(\frac D{v_0})\] Here is where I'm stuck: \[ma=qE\] \[a=\frac {qE}{m}\] \[KE=U\] \[\frac 12 mv_0^2=qV_acc\] \[v_0^2=\frac {2qV_acc}{m}\] now i Have \[\Delta y=\frac{qE}{m}(\frac{Lm}{2qV_acc})^2+L +D\]

Best ResponseYou've already chosen the best response.0but my equation should look like \[\Delta y=\Delta y_1+\Delta y_2=\frac{EL}{2V_{acc}}\left( D+\frac L 2\right)\]

Best ResponseYou've already chosen the best response.0I probably made a mistake somewhere, because my m's aren't cancelling out....and some other stuff too I guess

Best ResponseYou've already chosen the best response.0so we are supposed to get the initial xvelocity from the voltage generated by the AC, which you say is 500V. I don't know where you get that number, but if it is correct answer @experimentX 's question

Best ResponseYou've already chosen the best response.0yep .. it's called accelerating potential.dw:1362064638627:dw

Best ResponseYou've already chosen the best response.0I'm not worried about that anymore. do we know that the V_acc is exactly 500V or is there some uncertainty. should i mention that there is some uncertainty

Best ResponseYou've already chosen the best response.0this is how you accelerate electrons http://en.wikipedia.org/wiki/File:WaterCooledXrayTube.svg No it doesn't matter for theory. Just for error analysis ..

Best ResponseYou've already chosen the best response.0I"v never been good with error analysis ... but let's see what I can do.

Best ResponseYou've already chosen the best response.0hmm ... what methods are asked to use?

JenniferSmart1

Best ResponseYou've already chosen the best response.0he said to just describe the method but don't go into too much detail. I described it already and I just need to tweek a couple of things in my report to make it look better. The equations are fine I guess, I'll just use the final displacement equation without too just some derivation steps. Thanks for you help though. I'm not gonna learn anything new in the next 15 mins

Best ResponseYou've already chosen the best response.0okay .. I'll send you the details of derivation if you want ... within next 15 hrs. (optional: if you want)

Best ResponseYou've already chosen the best response.0Your this expression is incorrect \[ \Delta y_1=v_0\frac{L}{v_0}+\frac 12 a(\frac{L}{v_0})^2 \] \(v_0 \) is zero by default ... no ycomponent.
