The officer has a top speed of 100 km/hour, and the state line is only 2.00 km away. The cop wishes to reach the speeder just as she reaches the state line. The question is if the officer is to reach the woman right at the state line how fast must he accelerate? 1. Write an equation for the officer's motion during the time when his acceleration is zero? 2. which quantities in the above equation are not known? 3. Write an equation for the officer motion while he is accelerating write it using only one of the unknowns? 4. Write an equation for the officer motion while he is accelerating to write it using the other variable?
