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