How do you determine the force constant of a spring when given the mass of an object being hung vertically, and the distance the spring stretches? What formula and logic do I need?
Sorry, I forgot to mention the question also gives the period of the oscillations. This confused me.. why would I need that piece of information. Don't I simply use F=-kx, then mg=-kx and solve for k??
It appears to be oscillating, not hanging still. You cant use kx if it is moving.
But I don't understand where to go from here.
Do I use the formula T=2pi*sprt(m/k) ?
I'm just confused because it seems like I have an extra piece of info I should be using (in this case x).
