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

A 3Kg mass, attached to spring oscillates w/ amplitude of .15m and a period of 2s. At time t= 0.5s the objects position is .019m.

Find the total energy of the system

2. Relevant equations

(.5)mv^2+(.5)kx^2= (.5)kA^2

3. The attempt at a solution

I found the spring constant to be 29.6 N/m... my only question is this... (.5)mv^2+(.5)kx^2

would give me the answer, as would (.5)kA^2 correct? to get the total energy i just did (.5)(29.6)(.15)^2 = .333J

Is that correct???
