Question: When nine people whose average mass is 88 kg sit down in a car, they find that the car drops 1.42 cm lower on its springs. Then they get out of the car and bounce it up and down.
The acceleration of gravity is 9.8 m/s2 .
What is the frequency of the car's vibration if its mass (empty) is 1700 kg?
