When four people with a combined mass of 320 kg sit down in a car, they find that the car drops 0.70 cm lower on its springs. Then they get out of the car and bounce it up and down. What is the frequency of the car's vibration if its mass (when it is empty) is 2.0 * 10^3 kg?CAN SOMEONE HELP ME WIT THIS?

find the spring constant . use F = mg then F=constant times 0.7 . then find the frequency using this formula |dw:1321965724193:dw| where c is the spring constant, and m is the mass when the car empty
