but wait, for mechanical energy equations wouldn't i need m, v, or k...so I am utterly confused, can i ask you a favor of working the problem out so i can see what you mean?

i don't I am confusing myself, i will try mechanical energy.

thats what I've been trying to do, but I am not sure what way to find m/k one way is to use the equilibrium displacement equation, y = mg/k, but i didnt get the right answer from there

T=2pi/sqrt(m/k) ?

i could get the period from either 1/f or 2pi/omega...

how? to do that i need to know k, or omega, or something that I am not given

the total mechanical energy

if your referring to what does not change...g,m,k,T,f

the potential energy of the spring?

odd, using what you said to work it out, i got T=.108994, so something is wrong if we got different answers doing the same thing... nvm i forgot to sqrt the g/y, i did get the same value as you

tried your solution, still saying incorrect answer

nope... but I've been looking around and i think the equation yo = mg/k the one to find the difference in the equilibrium points of when there is no mass and when there is a mass. but i don't know if my algebra is bad but i rearrange and get y*g = k/m which is ω but i also have seen some do...

An object is hung on the end of a vertical spring and is released from rest with the spring unstressed. If the object falls 0.17 m before coming to rest, the period of the resulting oscillatory motion will be _____ s. im am uttlerly lost on this...

ahh i see, I have a ti-89 calculator, and i did my grouping wrong so it was doing things a little out of what i wanted it to lol, bad grouping on my part, but thanks a whole bunch!

umm i understand what your trying to say, but 4.39kg is wrong aswell
