a spring with k=33.5 n/m has 1.2kg mass attached it is pulled .12m and released how much mechanical energy does it have?

Assuming the system has no friction, it's a simple harmonic oscillator and therefore has constant mechanical energy. When the spring is fully stretched, all of that mechanical energy is spring potential
E = PS
E = ½kA²
E = ½33.5(0.12²)
E = 0.2412 J
E = 0.24 J
I hope this helps.
