Note for teacher

In order for this exercise to make sense, you want to disable the textfields for the initial conditions input and output. In order to do this and to set up the initial conditions for this exercise, the following JavaScript code is executed upon loading of this web page:

function initialize() {
  simulation.jsSetVisible("no","V0Box");
  simulation.jsSetVisible("no","AlphaBox");
  simulation.jsSetVisible("no","setup");
  simulation.jsSetVisible("no","MBox");
  simulation.jsSetVisible("yes","TrackmarksBox");
  simulation.jsSetVisible("no","Reset");
  simulation.jsSetVisible("no","BodyChoice");
  simulation.jsSetM(0,100000);
  simulation.jsSetM(1,100);
  simulation.jsSetM(2,20);
  simulation.jsSetM(3,30);
  simulation.jsSetAlpha(0,0);
  simulation.jsSetAlpha(1,180);
  simulation.jsSetAlpha(2,90);
  simulation.jsSetAlpha(3,270);
  simulation.jsSetV0(0,0);
  simulation.jsSetV0(1,10);
  simulation.jsSetV0(2,100);
  simulation.jsSetV0(3,100);
  simulation.jsSetXY(0,140,170);
  simulation.jsSetXY(1,480,40);
  simulation.jsSetXY(2,1000,170);
  simulation.jsSetXY(3,2000,170);
  simulation.jsSetXY);
  simulation.jsReset();
  simulation.jsStart();
