1. The problem statement, all variables and given/known data A speeding motorist traveling 120 km/h passes a stationary police officer. The officer <i>immediately</i> begins pursuit at a constant acceleration of 10.0 km/h/s. How much time will it take for the police officer to reach the speeder, assuming that the speeder maintains a constant speed? How fast will the police officer be traveling at this time? 2. Relevant equations These are the equations we have to pull from in class: Vf=Vi + at D= Vit + 1/2at2 D=1/2t (Vf+Vi) Vf2=Vi2 + 2aD 3. The attempt at a solution I fixed the mixed units so that 120 km/h equals 33.33 m/s and 10 km/h/s equals 2.778 m/s2 The officer's Vi is 0. Distance(D) of the motorist and Distance(D) of the officer should be the same, as well as their times(t). So, Dm=Do and tm=to I've tried solving the above equations for a distance or a time that i can then sub back in, but nothing seems to be working. I just need a little push in the right direction.
