**Robert**, Monday, December 13, 2010 at 1:13amCan't figure it out. Does it have something to do with finding w?

w=2pi/T = square root of k/m but I don't have K or T?

**drwls**, Monday, December 13, 2010 at 2:55amUse the information provided to get the natural (and resonant) frequency of the suspension system with a total mass of M = 1205 kg. From that you can derive the spring constant, k.

f = [1/(2 pi)] sqrt(k/M)

The natural frequency will be the rate at which the car goes over washboard bumps at the resonant (maximum amplitude) condition.

When the people get out, the car body will rise by an amount

(80 kg)(9.8 m/s^2)/k
