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 you to answer the above question time
4. An object is launched vertically upward from the ground and follows the following equation where x is vertical height in meters and t is time in seconds. x=25t-512 (a) What is the initial position at-07(This is the ground position.) (b) At what later time does the object return to the ground? (c) Find an equation for the velocity of the object (d) Sketch velocity vs time on the axes provided. (e) What is the initial velocity of the object? (t) At what time does the object reach maximum height? (g) Find an equation for the acceleration of the object (h) Sketch acceleration vs time on the axes provided.
