An unmarked police car traveling a constant 85 km/h k m / h is passed by a speeder traveling 135 km/h k m / h . Precisely 1.00 s s after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 2.50 m/s2 m / s 2 , how much time passes after the police car is passed by a speeder and before the police car overtakes the speeder (assumed moving at constant speed)?

Calculate the first and second velocities of the car with four washers attached to the pulley, using the formulas v1 = 0.25 m / t1 , and v2 = 0.25 m / (t2 – t1) where t1 and t2 are the average times the car took to reach the 0.25 and the 0.50 meter marks. record these velocities, to two decimal places, in table e.
