Four identical springs are used as part of a car's system, one on each wheel. The spring's compress by 8cm, when the weight of the car is 1800 kg car is applied to them.
a. what is the spring constant of each of these springs?
b. what will be the frequency at which the car will bounce?
c. if two of the springs break down and fall off, what will be the frequency at which the car will bounce?
