A car travelling at a constant speed of 136 km/hr passes a tropper hidden behind a billboard. One second after the speeding car passes the billboard, the tropper sets in a chase after the car wit ha constant acceleration of 3.8 m/s^2. How far does the trooper travel before he overtakes the speeding car?

The distance traveled is the same.
distancespeeder: velocity*time change 136km/hr to m/s
distancetrooper: 1/2 3.8 (t-1)^2

set them equal, solve for t. then, go back and solve for distance in either equation
