The shock absorbers in a car with a mass of 979 kg are completely worn out. When a 930 N person climbs slowly into the car at its center of gravity, the car sinks 3.8 cm. The car (with the person aboard) hits a bump, and the car starts oscillating up and down in SHM.
Model the car and person as a single object on a single spring, and find the frequency (in Hz) of the oscillation.
