Question

A mass oscillates on a horizontal spring in a simple harmonic motion. It is observed that the duration of one full oscillation cycle is 0.50 π seconds, and that the maximal displacement of the oscillator from the equilibrium is 12.0 cm. Let time instant taken as t = 0.00 sec correspond to the moment when the mass is at the location 10.0 cm to the left of the equilibrium, and moving to the left.

A) A mass on a spring vibrates in simple harmonic motion at a
frequency of 4.0 Hz and an amplitude of 8.0 cm. If a timer is
started when its displacement from equilibrium is a maximum (hence
x = 8 cm when t = 0), what is the displacement of the mass when t =
3.7 s?
B) A mass of 4.0 kg, resting on a horizontal, frictionless
surface, is attached on the right to a horizontal spring with
spring...

A simple harmonic oscillator consists of a mass of 100g attached
to a constant spring is 10^4 dynas/cm. At time t=0, the mass is
about 3 cm from the equilibrium point and with an initial velocity
of 5cm/s, both in the positive direction.A dissipative force is now
added. Assume that you start moving from rest at the maximum
amplitude position, and after oscillating for 10 s, your maximum
amplitude is reduced to half of the initial value. Calculate:
A- dissipation...

Let’s think back to the lab for simple harmonic motion. Consider
the setup for the simple pendulum. The length of the pendulum is
0.60 m and the bob has inertia 0.50 kg (assume mass of the string
is negligible, and small angular displacements). You conduct two
experiments (A and B) to investigate the physics of simple harmonic
motion. For experiment A, you pull the pendulum 5 ◦ , or π 36
radians. In experiment B, the angular displacement is 10◦...
