Part A Now play the video once again. Observe the graphs of the horizontal acceleration and vertical acceleration against time. How do the two graphs, ax vs. t and a y vs. t appear? What can you say about the acceleration of the snowboarder? Part B Now, change the two graphs to display the horizontal and vertical component of velocity versus time. What do you observe about the velocity components of the snowboarder, before and after time t = 0?

Part C From the graph of the horizontal velocity against time, what can you say about the horizontal displacement of the snowboarder after time t = 0?

Part D From your observations about the vertical velocity and acceleration, what can you say about the vertical displacement of the snowboarder after time t = 0?

Part E Based on your analysis of the snowboarder’s motion, how do you think you could get even better results from a center of mass measurement like this one?
