Problem and project: Six groups of four students are given stop watches and a measuring tape in order to plan and set up, within ten minutes, an experiment to utilize measuring strategy to  determine the speed of ten vehicles that pass by (without use of a speedometer).

Procedure:

1. We first measured the distance between where we began to time the vehicles and where we stopped timing the vehicles
2. We then stood at the end of the distance we measured with stop watches and alternated which of the two timers recorded each car (in case there isnâ€™t enough time to reset) one timer measured the even cars and the other timer measured odds.
3. We then began to time the cars when they passed the starting point and stopped timing them when they passed us, all the while recording the data
4. When we reached ten cars we went inside, complied our data, and determined the speed of each by using the formula for speed: v= d/t

Our results showed that most of the cars stayed around the 9-14 meters per second range. To improve our data we could have measured to the center of both of the trees instead of to the general area in front of them. We could have also done multiple versions of the same car at the time to take an average and lower the risk of over or under timing the car (a mistake made by one person).

There is not a speeding problem on cooper. Through our data gathered in meters per second we saw that no cars went over 14 meters per second, the speed limit on cooper (which is 35 mph) when converted to meters per second is around 15. There is not a speeding problem on cooper because all the cars stayed within the 35mph speed limit.
