Answer to Question #149341 in Physics for Reanna Mollino

Question

A 200 g undamped oscillator placed in a vacuum is observed to have a frequency of 2 Hz. This is the same system as in Question 1 with the same initial conditions. Air is admitted to this system and the oscillation decreases to 60% of its initial amplitude in 50 s.
For this system, determine the:
Damping coefficient γ.
Angular frequency.
Quality factor and the type of damped system.
Period.
Displacement equation x(t) in the form x(t)=A cos⁡〖(ωt+ϕ)〗.
Displacement at t=50 s.
Velocity at t=50 s.
Acceleration at t=50 s.
Potential energy at t=50 s.
Kinetic energy at t=50 s.
Restoring force at t=50 s.
Resistive force at t=50 s.
