Muskkan Posted February 18, 2020 Share Posted February 18, 2020 Can someone answer this: A critically damped simple harmonic oscillator starts from an amplitude of 5.0 cm and comes to rest at equilibrium 3.5 sec later. The simple harmonic oscillator is made of a .58 kg mass hanging from a spring with spring constant 150 N/m. Assuming the friction force is in the vertical direction, how big is the friction force?

FizziksGuy Posted February 18, 2020 Share Posted February 18, 2020 Hi Muskkan. Damped oscillators are outside the scope of AP Physics 1/2, but happy to help if I can. How far have you gotten so far / where are you getting stuck? Quote Link to comment Share on other sites More sharing options...
Muskkan Posted February 18, 2020 Author Share Posted February 18, 2020 Well, in AP Physics class we are using Giancoli 6th edition book. It doesn't have equations for Damped simple harmonic oscillator. I looked at the following link: http://farside.ph.utexas.edu/teaching/336k/lectures/node19.html but I do not know how to get started. The given are Amplitude = .05 m, Time = 3.5 sec, Mass = .58kgs, k = 150 N/m and we nee to find Friction force. Quote Link to comment Share on other sites More sharing options...
FizziksGuy Posted February 20, 2020 Share Posted February 20, 2020 I might start with a resource like this: https://opentextbc.ca/physicstestbook2/chapter/damped-harmonic-motion/ or this: https://www.toppr.com/guides/physics/oscillations/damped-simple-harmonic-motion/ Quote Link to comment Share on other sites More sharing options...
