Homework Help: Another police chase

  1. Sep 3, 2009 #1
    1. The problem statement, all variables and given/known data

    A car traveling at a constant speed of 129 km/hr passes a trooper hidden behind a billboard. One second after the speeding car passes the billboard, the trooper sets in a chase after the car with a constant acceleration of 2.7 m/s2. How far does the trooper travel before he overtakes the speeding car?



    2. Relevant equations

    d= v(initial)t + .5at^2


    3. The attempt at a solution

    d= 35.83m/s(t) + .5(2.7)(t)^2 + 35.83

    I don't understand what needs done, thanks

    What is the position of the trooper at time t?

    What's the position of his target at time t?

    When are they in the same place?
