i suspect firefox 3 on Mac osx is giving me this problem.
i tried safari on Mac osx  nope it also didn't load as well
Yes, you are correct, the above applet does load properly even with Windows 1gb ram, take some time but work well:)

Question:how to make the simulation more like fall and rebounce ?
i have this technical problem,
to make T[4] = 10 and T[6] = 10.
but it will screw up the rest of the calculation for acceleration etc....
any simple way to make the simulation more like a fall and rebounce on a hard surface ?

but i don't want to affect the original codes for the rest of the options.

any tips?  ;D tricky right?
