A spring of spring constant 30.0N/m is attached to different masses and the system is sent in motion find the period and frequency of vibration for masses of the following

Which of the following is not a part of the respiratory system? a. pharynx b. trachea c. pancreas d. larynx

Photons with the highest energy have the longest period

Suppose that a mass of 2 kg is attached a spring whose spring constant is 50. the system is damped such that b = 12 . the mass is set in motion with an initial velocity of -8 m/s at a position 0 meters from equilibrium. set up and solve a differential equation that models this motion. write your solution in the form a cos ( ω t − α ) where α is a positive number. use your solution to fill in the information below: what is the amplitude of the motion? what is the value of ω ? what is the phase shift?
