## Homework Statement

A 94.0 kg man climbs onto a car with worn out shock absorbers and this causes the car to drop down 5.90 cm and comes to equilibrium. As he drives along, he hits a bump, and this starts the car oscillating at an angular frequency of 4.65 rad/s. What is the mass of the car?

## Homework Equations

## The Attempt at a Solution

I found the spring constant using newtons 2nd law, k=mg/x =1563N/m

angular frequency = [tex]\sqrt{k/m}[/tex]

m=1563/21.6 = 72.4kg

72.4kg x 4 = 289kg b/c its distributed by 4 shocks.. but not the right answer.. def missing something
