Homework Statement
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
Homework Equations
a. T=2pi[tex]\sqrt{}m/k[/tex] m=Tk/4pi2' T=1/f
b. a=-kx/m ?
The Attempt at a Solution
a.T=1/f T=1/0.148Hz T=6.756756757s m=Tk/4pi2' m=(6.756756757s)(2.56N/m)/4pi2' m=2.96kg ---- I do not understand if this is right and I think I made a mistake ----
b. I can't figure out what equation to use and how to manipulate it to get an equation for acceleration for the condition
