3. A car traveling at a constant 39 m/s (-87 mph) passes a police car that is initially traveling at 25 m/s (55 mph). At the instant of the pass, the police car accelerates at a constant rate of 3.3 m/s in pursuit. We wish to find how much time elapses before the officer catches the car. (a) Identify the initial states when the car passes the police. (b) Define the final state or conditions which enable...

2. A police car is traveling at a constant velocity of 20.0 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 0.800 s the policeman begins to pursue the speeder with an acceleration of 5.00 m/s?. Including the reaction time, how long does it take for the police car to catch up with the speeder? Sketch the position vs time plot for the two motions and show...
A motorist traveling with a constant speed of 15m/s passes a school-crossing corner, where the speed limit is 10m/s
A motorist traveling with a constant speed of 15m/s passes a school-crossing corner, where the speed limit is 10m/s. Just as the motorist passes, a police officer on a motorcycle at the corner starts off in pursuit with constant acceleration of 3m/s^2. (a)How much time elapses before the police catches up the motorist? (b)What is the officer's speed limit at that point? (c)What is the total distance each vehicle has traveled at that point?

A cyclist sprints at the end of a race to clinch a victory. She has an initial velocity of 11.3 m/s and accelerates at a rate of 0.610 m/s for 7.85 s. (a) What is her final velocity? (Enter the magnitude in m/s.) 16.089 m/s (b) The cyclist continues at this velocity to the finish line. If she is 300 m from the finish line when she starts to accelerate, how much time did she save (in s)? (c) The...

A race driver has made a pit stop to refuel. After refueling, he starts from rest and leaves the pit area with an acceleration whose magnitude is 5.2 m/s2; after 3.9 s he enters the main speedway. At the same instant, another car on the speedway and traveling at a constant velocity of 71.1 m/s overtakes and passes the entering car. The entering car maintains its acceleration. How much time is required for the entering car to catch up with...

An unmarked police car, traveling a constant 90.0 km/h, is passed by a speeder traveling 166.0 km/h. Precisely 3.40 seconds after the speeder passes, the policeman steps on the accelerator. If the police car's acceleration is 2.1 m/s2, how much time elapses after the police car is passed until it overtakes the speeder (assumed moving at constant speed)?
