i think this question should be in introductory physics section.. apologies! Mods please move this :)

Homework Statement Please find the question in the attachment,i've attached it because it includes a graph Homework Equations a=-(omega)^2.x T=2.pie/omega Vmax=omega.A The Attempt at a Solution for part b i used the first equation a=-(omega)^2.x to find omega and then substituted...

aah! great stuff,thanx.

I didn't get it.How do you find the angular frequency from the sinusoidal function of ma=-kx (or m d2x/dt2 = -kx ?

I guess you use the time period formula for pendulum T=2pie.sqrt(L/g)

F=-kx when talking about a mass at the end of a horizontal spring therefore ma=-kx rearranging we get a= -(k/m)x then it says if we define ω2=k/m we then have a generic form : a= -ω2x My question is what does "if we define ω2=k/m" mean? where does this come from?is it just any random...
