A car is traveling at –3 m/s at the position +10 meters at the time +5 seconds. a. Write the position function as a function of time for this car. A second car is traveling at –1 m/s at the position –5 meters at the time +8 seconds. b. Write the position function as a function of time for this car. c. Sketch the two functions accurately. Specifically, locate the x and y intercepts. Locate the time and position where...
Question 2 A car is traveling to the left at 20 m/s and it is accelerating to the left at a constant rate. After 5 seconds of time, the car is traveling to the right at 5 m/s. a. What is the acceleration of the car? b. How far does the car travel over the 5 seconds? Question 3 A stone is thrown upward.

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...
