(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Automobile of mass m=2000kg has a suspension that sags 10 cm when the entire auto is placed on it. The amp. of oscillation decreases 50% with every complete oscillation. Solve for (a) spring constantkand (b)the damping constantbfor one wheel (assuming each wheel supports 500 kg).

2. Relevant equations

F_{spring}=-ky

F_{drag}=-bv

y(t)=y_{max}e^{-bt/2m}

3. The attempt at a solution

I think i should use [tex]\Sigma[/tex]F=ma for the initial force, which would be gravity ant the spring. so mg=-ky then solve for k. i am not sure how correct this is, though. then for part b, i dont know what to do about t in the equation and i was considering using a variable (so t/2 for the 2nd oscillation)
