## Homework Statement

An oscillator consists of a block attached to a spring (k=400n/m). At some time

*t,*the position (from equilibrium), velocity, and acceleration of the block are x= .100m, v= -13.6m/s, a= -123m/s^2.

What is the frequency? mass of block? amplitude.

## Homework Equations

position function, velocity function, acceleration function

**3.The attempt at a solution**

The problem I'm having with this question is with part a. I understand the solution I looked up but what I don't understand is why I can solve for ω by rearranging v=ωx for ω=v/x? I know to use the acceleration formula a=(-ω^2)x and ω=√(a/x).

Is it that the velocity mentioned in the question is not the same form of velocity used in the velocity formula for SHM?

Any help would be much appreciated!
