A blue car moving at constant speed of 10m/s passes a polic car that is at rest. The police car accelerates from rest at 4m/s^2 for 3.0 seconds and then maintains a constant speed. The blue car maintains constant speed for the entire 12 seconds. When does the police car pass the blue car? Calculations: Blue Car: Vi= 10 m/s Vf = 10 m/s deltaT = 12 s deltaD = 120 m acceleration = 0 Police Car: Vi = 0m/s acceleration = 4m/s^2 (for the first 3 seconds) deltaD (for first three seconds) = 18 m Vf = 12 m/s So when the deltaD of the blue car = the deltaD of the police car, the police car is at the same distance as the blue car. How would I go about doing this?
