A sinusoidally carrying driving force is applied to a damped
harmonic oscillator of force constant k and mass m. If the damping
constant has a value b1, the amplitude is A1
when the driving angular frequency equals ?(k/m) . In terms of
A1, what is the amplitude for the same driving frequency
and the same driving force amplitude Fmax, if the
damping constant is (a)3b1 and (b)b1/2? The
oscillator is now at the resonace condition. If the damping

In Classical Physics, the typical simple harmonic oscillator is
a mass attached to a spring. The natural frequency of vibration
(radians per second) for a simple harmonic oscillator is given by
ω=√k/m and it can vibrate with ANY possible energy whatsoever.
Consider a mass of 135 grams attached to a spring with a spring
constant of k = 1 N/m. What is the Natural Frequency (in rad/s) of
vibration for this oscillator?
In Quantum Mechanics, the energy levels of a...

A simple harmonic oscillator is made up of a mass-spring system,
with mass of 1.31 kg and a spring constant k = 148 N/m. At time
t=1.66 s, the position and velocity of the block are x = 0.135 m
and v = 3.958 m/s. What is the amplitude, xm, of the
oscillations?
Your answer should be in m, but enter only the numerical part in
the box.
