Hi, I can't seem to work out this problem/ what formulas to use:
An object was suspended from the end of vertical spring and set into ocsillating motion along a vertical line with acceleration (a) at a displacement (x) was given by a=-360x. Calculate:
i) frequency
ii) time period of the oscillations.
The previous question, which it was related had a time period of 0.325sec ( 20 oscillations in 6.5 sec) and freq of 3.08Hz. [ checked with book answers]. They say the mass is changed in this question though.

Thank you!
You need to find ω to get the frequency. There is a formula that relates ω2 to the acceleration of the mass and its displacement from equilibrium. (It's the defining formula for SHM)

so w=2pi(f) and a=-w^2 x. i would work out f, but I dont know w? Sorry, I'm still a bit confused..
