(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

An object suspended from a spring with a spring constant of 2.56 N/m vibrates with a frequency of 0.148 Hz

a. What is the mass of the object

b. What is the acceleration of the object at a displacement of -0.120m from the equilibriam position

2. Relevant equations

a. T=2pi[tex]\sqrt{}m/k[/tex] m=Tk/4pi^{2}' T=1/f

b. a=-kx/m ????????

3. The attempt at a solution

a.T=1/f T=1/0.148Hz T=6.756756757s m=Tk/4pi^{2}' m=(6.756756757s)(2.56N/m)/4pi^{2}' m=2.96kg ---- I do not understand if this is right and I think I made a mistake ----

b. I cant figure out what equation to use and how to manipulate it to get an equation for acceleration for the condition
