A 2.7 kg block hangs at the end of a spring. When the block is at rest, the spring is stretched 0.38 m away from its equilibrium position. The block is set into simple harmonic motion and oscillates with an amplitude of 0.24 m. What is the total energy of the block/spring system?

Relevant equations

there are also PE and KE energy equations...

There are also the PE and KE equations...but they are kinda long (since i'm still a newbie at latex)
