Do you guys know of any program that can give me the radius of a circumference, if I input the cartesian coordinates of some points?

Thank you guys, I understand it all now :woot:

Could it be (l1/l0)k1=k ?

I'm guessing the shorter one has a higher spring constant. Could it be l1k1+l2k2=l0k (where this k is the one used for the angular frequency)? l1 is the distance between the left vertical stick and the mass, and l2 is the distance between the mass and the right stick.

There is a delay because, when I change the voltage, the time that I measure changes as well. I need to add a correction into my calculations so that I can get a better result, but I don't know how.

When you have a metallic ball hanging from a electromagnet and you disconnect the electromagnet, there is a delay between the moment you unplug the machine, and the ball starts falling. Why does this happen?

@Orodruin So the spring constant relevant for computing the angular frequency is the one that obeys k=k1+k2, and the spring constant of the full spring obeys 1/k=1/k1+1/k2, right?

I always heard that magnetic forces don't do work, and that they act perpendicularly to the direction of movement.

I guess it is k=k1+k2, because when you move it Δx, the force acting on it is -(k1+k2)Δx, right?

Homework Statement We have a spring of length l0 tied to two vertical non moving sticks. We place a mass m at 0,45l0 and let it oscillate. If we measure the period of an oscillation, we can find the angular frequency and calculate k. The question is, how can I calculate k1 and k2, the constants...
