Total energy for a simple harmonic oscillator:
Potential energy U = (1/2)kA2
Kinetic energy, K = (1/2) mv2
If the kinetic energy, K = (3/4)E, we have:
An object of mass m attached to a spring of force constant k oscillates with simple harmonic motion. The maximum displacement from equilibrium is A and the total mechanical energy of the system is E.
What is the system's potential energy when its kinetic energy is equal to 3/4 E?
