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

A simple harmonic oscillator has spring constant k = 7.8 N/m, amplitude A = 12 cm, and maximum speed 4.3 m/s.

What's the oscillator's speed when it's at x = 5.4 cm?

2. Relevant equations

KE_max=1/2*k*A^2

KE=1/2mv^2

ma=-kx

v=k/ma

3. The attempt at a solution

I used each equation in order to find the K_max, the mass of the oscilator, the acceleration, and then the velocity in that order, but the answer I got was wrong.
