Question: A compact car has a mass of 1310kg . Assume that the car has one spring on each wheel, that the springs are identical, and that the mass is equally distributed over the four springs.
Part A: What is the spring constant of each spring if the empty car bounces up and down 1.80 times each second?
Part B: What will be the car's oscillation frequency while carrying four 87.0kg passengers?
