woah, that solved all the problems...like even my other ones similar to this one, you are a lifesaver...i think, idk, we'll see the results later. although...my other has me finding the x(max)...which I'm finding to be almost impossible again
well...we aren't allowed to use energy conservation yet because we haven't learned it. If u could help correct what i have, that would be the best way. But i don't understand what u mean by avaerage force and stuff. isn't everything at an instant?
Oh, i did a very similar lab to this one. Anyways, your answers is correct and i think it is so because as the stopper spins faster, it gets harder to count the revolutions and stop the timer at the exact time of the revolution occurring.
It seems right in the thinking but once you consider the conservation of energy, then it seems flawed. i believe the sum should still be 0...somehow..idk how else u could prove it cept with PEi + KEi = KEf + PEf >>>>>>0 = PEf + KEf
I need help ASAP because the teacher assigned it today and its due tomorrow...
