Question: A shock absorber is designed to quickly damp out the oscillations that a car would otherwise make because it is suspended on springs. Part A Part complete Find the period of oscillation of a 1680-kg car that is suspended by springs that make an effective force constant of 6.15×104N/m. Express your answer to three significant figures and include appropriate units. 1.04 s Previous Answers Correct Part B Find the damping constant b that will reduce the amplitude of oscillations of this car by a factor of 6.00 within a time equal to half the period of oscillation. Express your answer to three significant figures in kg/s. nothing kgs
