Question

A 0.25 kg harmonic oscillator has a total oscillation energy of 4.0 joules. If the oscillation amplitude is 20.0 cm, what is the oscillation frequency?

A 0.39 kg block on a horizontal frictionless surface is attached to a spring whose force constant is 570 N/m. The block is pulled from its equilibrium position at x=0 m to a displacement x=+0.080 m and is released from rest. The block then executes cineplex harmonic motion along the x axis. When the displacement is x=0.057 m, the kinetic energy of the block is........?

Explanation / Answer

k = 2E / A
