After a few attempts to get his cycle started, the officer roars off 2.00 seconds later. The officer has a top speed of 100 km/h and the state line is only 2.00 km away. The cop wishes to © Teach the speeder just as she reaches the state line. e la) Draw a picture for the case of the woman in the Ferrari. Show 2 important points on the x-axis.

The starting point (Zo, to, U.), the point where he reaches 100 km/hour (z;, t;, v1) and the point, where he catches the speeder(22, ta, v2). At each point, label the time, the position and the velocity of the cop. Label the acceleration between the first 2 points as a, and the accceleration between the last two points as a2.
