A police car is traveling at a velocity of 19.0 m/s due north, when a car zooms by at a constant velocity of 45.0 m/s due north. After a reaction time of 0.700 s the policeman begins to pursue the speeder with an acceleration of 5.30 m/s2. Including the reaction time, how long does it take for the police car to catch up with the speeder?
