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

Calculate the total energy of a 2kg mass that is undergoing simple harmonic motion with an amplitude of 1cm and and frequency of 16Hz.

2. Relevant equations

ma = -w^{^2}x

3. The attempt at a solution

The first thing I thought was using the general solution of x(t) = A cos(wt + psi), differentiating to find the velocity (after the phase angle, or is this even needed?), and then using the value in K.E = 1/2mv^2?

Please help!
