Homework Help: Acceleration and time

  1. Aug 23, 2015 #1
    1. The problem statement, all variables and given/known data

    A motorcycle cop, parked at the side of a highway reading a magazine, is passed by a woman in a red Ferrari 308 GTS doing 176. km/h. After a few attempts to get his cycle started, the officer roars off 2.00 s later and catches the Ferrari at the state line 2.00 km away some time after attaining his top speed of 211. km/hr. What was his acceleration during the time he was accelerating?

    2. Relevant equations
    I thought total time should be provided to be able to solve this problem, but it is not.
    So I got really stuck..

    3. The attempt at a solution
    If the total time is given, I would put 2000m as delta position(dx) and use the acceleration equation (v0t + 0.5at^2).

    I would appreciate any help! Thanks!

    What's stopping you calculating the time? Hint: there are two vehicles involved.
