Speeding Lab

In this lab we participated in the Irondequoit Police Department Safety project; our goal was to gather data about the speeds of cars driving down Cooper road. The speed limit in front of the high school is 35 mph or 15.6m/s. We measured the speed of 10 vehicles driving North on Cooper road. The only materials that we had were stopwatches and a tape measure. We needed to problem solve in order to find the speeds of the car using two measurements.

First we drew a rough draft of how the graph should look, then we created a data table with measurements and decided on a distances (15.6, 31.2). Then we walked downstairs and put down the measuring tape and gave each individual a job and someone would yell start and time the cars speed from 0 to 15.6 and then had another person yell start in order to time the cars speed from 15.6 to 31.2.  From there our group did the process ten times and collected all the data.

The average speed of all 10 vehicles was calculated by taking the distance and dividing it by the time. We divided 15.6 by 6.6 and 1.6.  After we averaged the two to create an average speed; we added 6.6 and 1.6 and divided by two to get 18.05.

Our results were under the average speed limit. The car that was going the fastest was the Lincoln; it was going an average speed of 16 meters per second. The lowest speed was the West Irondequoit truck and it was 5.06 meters per second. To improve our result we could’ve used a radar gun and recorded more cars at different distances.  

According to our results, there is no speeding problem on Cooper road. Most of our vehicles (90%) were under the speed limit. Only one car was over the speed limit.  Based on the data, it’s proven that there’s no speeding problem on Cooper road.
