The experimental graphs of x vs. t, v vs. t and a vs. t that are displayed on the computer are shown here: 2.07 1.5- 1.0- Position (m) 0.5- 0.0 Time (s) N Velocity (m's) (2.619, 0.42) Time (s) 2- Acceleration (mis?) Time (s) Compare your predicted graphs and experimental graphs. Discuss any discrepancies. Is the cart moving with constant velocity or is it accelerating? How do you know? Explain. If you decided it was accelerating, is the acceleration constant or not? How do you know? What is the sign of the velocity as indicated in the v vs. t graph
