A mass-on-a-spring system has a spring constant k = 384 N/m and a mass m = 0.51 kg.

(a) If it is given an initial displacement of 0.22 m and then released, what is the initial potential energy of the oscillator? = 9.29 J

(b) What is the maximum kinetic energy of the oscillator? ____ J

I need help with part B, please explain!

After release, there is no more energy input, so the sum of potential and kinetic energies

= constant

=9.29 J

At the equilibrium position, the potential energy is zero, so the kinetic energy is at its maximum and equal to ______ J.
