speeding lab

Recommended Posts

For this lab we had to record the speed of the cars in front of the high school in a thirty meter distance. The speed limit is 35 mph, or 15.6 m/s. To complete this lab we measured out 30 meters and had someone at the start and finish of it, and the first person would raise their hand when a car came and the person at the end would time it from that point until it reached them at the end of the 30 meters. Then we would record the time. We did this ten times.

1. V= d/t V=30m/2.36s V=12.7m/s

2. V=d/t V=30m/1.92s V=15.6m/s

3. V=d/t V= 30m/2.67s V= 11.23m/s

4. V=d/t V= 30m/1.84s V= 16.3m/s

5. V=d/t V=30m/2.06s V=14.6m/s

6. V=d/t V=30m/2.53s V= 11.9m/s

7. V=d/t V=30m/3.02s V= 9.93m/s

8. V=d/t V=30m/2.29s V=13.1m/s

9. V=d/t V=30m/2.23s V= 13.5m/s

10. V=d/t W=30m/2.28 V=13.2m/s

The average speed of all ten vehicles is 13.2m/s.

From this lab our group learned that the cars are going at a limit under the speed limit except the second car was going the exact speed limit. We also learned that the spot we were located wasn’t a good spot because there were two stop lights right near us as well as a police car near us. That would make people go the speed limit and under so they don’t get pulled over. Next time if we were to do redo this lab we would find a better spot where there aren’t any stop lights and where there wasn’t a police officer.

            I don’t think we could properly answer the question of “is there a speeding problem on Cooper Road” because there were too many discrepancies. From our data though, there is no speeding issue because only one person out of the ten was going over the speed limit. People don’t usually speed as much in front of schools because that’s dangerous and there were kids down by the road. In short, I don’t think Cooper Road has a speeding issue.
