A shock absorber is designed to quickly damp out the oscillations that a car would otherwise make because it is suspended on springs. Find the period of oscillation of a 1590-kg car that is suspended by springs that make an effective force constant of 5.55×104N/m. Find the damping constant b that will reduce the amplitude of oscillations of this car by a factor of 5.00 within a time equal to half the period of oscillation.
