A highway patrol car traveling a constant speed of 125 km/h is passed by a speeding car traveling 140 km/h. Exactly 1.00 s after the car passes, the highway patrol officer steps on the accelerator; if the patrolman's car accelerates at 1.50 m/s2, how much time passes after the car passes before the patrol car overtakes the speeder (assume the speeder is moving at constant speed)
