2. Looking at your graph, what can you conclude regarding the motion of the car? 3. What is the speed of the car? How did you find it? 4. Your graph of position vs. time is a line with a constant slope. The equation for a line is y = mx + b. Write the physical quantities from your experiment that correspond to parameters: y, m, x, and b.
