"Report to the Principal"

Aim: To see if there are any cars that drive above the set speed limit outside of school [HHS]

Method: 

1. Measure the distance between 2 power poles = 50m 
2. Time how long it takes a car to travel this distance.
3. Collect 10 times.
4. Calculate speed in m/s - convert to km/hr
5. Are there any speeders?

Person/ s needed:

• "Flag Person" indicates when a car passes their pole
• "Timer Person" starts when a car passes their pole and stops when indicated by "Flag Person".
• "Writer Person" writes down the times

Speed	Car 1	Car 2	Car 3	Car 4	Car 5	Car 6	Car 7	Car 8	Car 9	Car 10	Average
Time (s)	04.69	3.59	4.50	4.40	5.40	4.15	6.09	3.77	3.43	5.02	4.504
m s-1	0.6	13.9	11.1	11.3	9.25	12	13.2	14.5	9.96	8.21	11.402
km hr-1	38.1	50	39.90	33.3	43.2	29.5	47.5	52.2	35.8	40.9	46.01

Conclusion: With the speed limit of 50kmph there was a singular car in the 10 measured to have gone above the speed limit. Though the tolerance could perhaps not acknowledge such with only 2kmph above the set speed. Through the investigation, we have discovered that the average speed of a car going past the school is around 46.01kmph or simply 46kmph which is under the speed limit.  With the exception of 1, all were going at a relatively slow speed--in technicality, the vehicle which got 52 kmph was indeed speeding but not to an extent in which a worry would surface. Improving our measuring method could perhaps make the investigation more accurate, such as recording more vehicles and being more certain with the timing. Increasing the diversity of the cars could help this as well; bigger cars, older models, newer models and the likes. Using proper equipment will improve the individual accuracy of testing a car also. Other methods may include speed cameras, light detection, etc.
