I hope that I construct this problem correctly. I am trying to....um, help a friend fight a speeding ticket. Thanks in advance for any help. The posted speed limit was 25 MPH. The officer was stopped at an intersection as I passed by him on the perpendicular and "estimated" that Iwas traveling "in excess of 35 MPH." He stated that by the time HE reached the next intersection, which is ~300 feet from his starting point, he had "paced" me at ~35 MPH and "activated his emergency lights and signalled" me to stop. I have already determined that if I was traveling at 37 MPH it would equal 54.25 ft/sec and therefore the distance would have been covered in about 5.42 seconds. I have also assumed that he would have had to pace me for SOME period of time (2-3 seconds) leaving only 2.42 to 3.42 seconds in which to catch up to me from the time that I crossed his path. What I am having trouble determining is: 1. How rapidly would he have had to accelerate in order to catch up to me ? 2. To what velocity would he have had to accelerate in order to catch up to me?
