An unmarked police car traveling a constant 95 km/h is passed by a speeder traveling 120 km/h. Precisely 1.00 sec. after the speeder passes, the police officer steps on the accelerator; if the police car's acceleration is 1.90 m/s^2 , how much time passes before the police car...

A truck on a straight road starts from rest, accelerating at 2.00 m/s2 until it reaches a speed of 32.0 m/s. Then the truck travels for 76.0 s at constant speed until the brakes are applied, stopping the truck in a uniform manner in an additional 5.00 s. What is the average ...
