Speeding lab

Recommended Posts

               The problem being solved in the lab was to see if people were speeding in their cars down Cooper road. The speed limit on this road was 35 mph (15.6 m/s). In order to find their speed we measured out 30 meters along the road on the sidewalk. We had people stand on the starting and ending point with stop watches to record the time it took the car to travel the given distance. When a car approached the starting point, one person would raise their hand to signal the person standing at the end of 30 meters to start the time. Once the car reached 30 meters, we stopped the time and recorded the time. There was a person standing in the middle of the 30 meters, describing each car that we recorded the time for. The table we created had three columns displaying the  vehicle number (1-10), a description of the car and its speed.  The average speed of all the cars was 12.12 meters per second.

                After recording all the data from each car, the results showed that every car did not exceed the speed limit. In the beginning, the cars were going below the speed limit due to the cop car that had pulled someone over. After time went on, the cop car had left and the cars started to pick up their pace. To improve our results, we could’ve gone to a busier street or even tried to collect data from a highway. We also could’ve been on a street that had a wider range between stop lights. Lastly, to get a more accurate speed of the car, we should’ve been hidden so the cars wouldn’t become distracted and slow down.

                According to our data, there isn’t a speeding problem on Cooper Road. The cop car affected the overall speed each car was going, because everyone had slowed down. Also, since we were measuring the speed out in the open, people were slowing down to observe what we were doing.  Overall, today no one was speeding on Cooper due different outside influences.
