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

speeder passes a police car at 34 m/s. Police car from rest accelerates with a uniform acceleration of 2.2 m/s^2. How much time till the police car overtakes the speeder?

2. Relevant equations

V=Vi + at

X=Xi +Vit + 1/2at^2

a= 2.2m/s^2 V=34m/s Vi=0

3. The attempt at a solution

not sure what equation to use, I think the second one just because it's a question passed on position. Vi=0 so the equation then would be t^2 = 2(X-Xi)/a, but where do I get X and Xi from?
