Group D: Hudson and Maren
Purpose: The purpose of the lab was to find the point of intersection between two cars from different groups. The cars accelerated from rest from different starting points, and using our data we predicted the point where they would collide.
Materials: Chalk, 2 Fan carts, timer, meter stick
Lab Description: Our group lost our work but however, received our original information from Group D (who had the opposing cart whose collision we predicted). Using this data we calculated our prediction for collision point.
Group D- Initial velocity was Vi:-.18
Starting point: 1m away from motion sensor
Group D then plugged these values in the equation:
∆x=1/2a(∆t)^2+(-.18)(t)
The found the value 4.3 seconds.
Our group found our initial velocity and plugged it into the same equation.
This equation produced: ∆x=1/2(.1203)^2+(.18)(t)
After testing our estimates to find the point of intersection, we found these values.
We predicted:
Cart C: 97cm
Cart D: 1.072m
Percent error: 0%
The results showed an intersection at exactly our predicted distance, therefore our group had zero percent error.
