The purpose of this lab was to take two fan powered cars with different accelerations going in different directions, and try and predict where and when they would collide.
Materials:
- Fan Powered Car
- Stop Watch
- Meter measuring stick
- chalk
Procedure:
We started the lab by finding the acceleration of our car. We did this by marking the displacement of the car at each second of motion. We then shared our data with another group so we could calculate the point of intersection. Once we compared data, we manipulated the accelerations to find where and when the two cars would collide.
Raw Data:
Time Their Data Our Data
Manipulated Data:

Summary:
We collaborated with Miranda and Morgan's group to find the position and time of intersection. They were our partner group, so we were able to use the same test and the same numbers as them. We ended up being within the allowed 5% error margin at the end of the experiment.
Prediction:
Time: ~2.5 seconds
Position: ~61 cm
Actual:
Time: 2.9 seconds
Postion: 63 cm
