Waves/thermodynamics

1. The problem statement, all variables and given/known data

How much energy must the shock absorbers of a 1240 kg car dissipate in order to damp a bounce that initially has a velocity of 0.840 m/s at the equilibrium position? Assume the car returns to its original vertical position.

2. Relevant equations

Fs = -kx

The spring equation is he only thing that comes even close to making sense.

3. The attempt at a solution

I honestly don’t know how to even get started, do I use the spring equation or something else. We covered thermodynamics and waves recently so it has to be from there, I just can’t find any equation that would work.

Thanks
