Objective Statement: We are looking for when a fast buggy and slow buggy intersect at a certain distance at 180cm. One buggy will start at 180cm and go in a negative direction at a fast pace and one buggy will start at 0cm and go in a positive direction at a slow pace.
Procedure: We will first, measure the speeds of the buggies using our phone as timers and a meter stick to measure distance. After we get the speeds of the buggies, we will then place the fast buggy at 180 cm and the slow buggy at 0 cm. We will then start the buggies at the same time and see if they intersect each other at the same place it says graphically.
Data Analysis:
Slow Buggy (100cm)
|
Fast Buggy (100cm)
|
5.97sec
|
2.74sec
|
6.36sec
|
2.49sec
|
6.47sec
|
2.44sec
|
Average: 6.27sec
|
Average: 2.56sec
|
100cm/6.27sec=15.95cm/sec
|
100cm/2.56sec=39.06cm/sec
|
Now that we figured the speeds of the buggies, we found out graphically where the two buggies would meet if we placed the fast one at 180cm and the slow one at 0cm. We made the fast buggy's slope negative because it is going in a negative direction and made the Y-intercept 180 because the starting point is 180cm. good!
After we graphed the equations, we found out that the buggies would intersect at 52.191cm because that is the Y-value where the lines on the graph intersect.excellent!
After we tested graphically, we tested with the actual buggies. The buggies met at a very close point to 52.191cm.
Conclusion:
I conclude that the buggies met at a close enough point to where it was the same as the graph. We may have had problems like reaction time and the straightness of the buggies, but in general the buggies met maybe only 1 or 2 cm from exactly 52.191cm. The lab was very successful.great job!
