1. The problem statement, all variables and given/known data A compact car has a mass of 1300kg. Assume that the care has one spring on each wheel, that the springs are identical, and that the mass is equally distributed over the four springs. a.) What is the spring constant of each spring if the empty car bounces up and down 1.4 times each second? b.) What will be the car's oscillation frequency while carrying four 90kg passengers? 2. Relevant equations 3. The attempt at a solution I know for part a I will use f = 1/2pi [sq rt (k/m)], which will be k = m (f2pi)^2 when rearranged. I'm just not sure what the frequency would be.
