Storm Runner: Mass: 10,660 kg Average Velocity: Slope of graph  = 17.67 m/s

Average Acceleration: (Change in Slope)/(Change in Time) = 0 m/s^2 Momentum: mv <span style="font-family: Arial,Helvetica,sans-serif;"> = 10,660(17.67) <span style="font-family: Arial,Helvetica,sans-serif;"> = 188,362.2 kg*m/s <span style="font-family: Arial,Helvetica,sans-serif;">Kinetic Energy: KE = 1/2mv^2 <span style="font-family: Arial,Helvetica,sans-serif;"> = ½(10,660)*(17.67)^2 <span style="font-family: Arial,Helvetica,sans-serif;"> = 1,664,180.04 J

<span style="font-family: Arial,Helvetica,sans-serif;">The data looks reasonable, especially since the video shows the Storm Runner as it is approaching the end of the ride. The constantly velocity also matches the video because there did not exist any noticeable speeding or slowing of the ride.

<span style="font-family: Arial,Helvetica,sans-serif;">Average Acceleration (x): (Change in Slope)/(Change in Time)

<span style="font-family: Arial,Helvetica,sans-serif;">Average Acceleration (y): (Change in Slope)/(Change in Time)

<span style="font-family: Arial,Helvetica,sans-serif;">= CANNOT BE FOUND due to lack to time with LoggerPro to find instantaneous slopes <span style="font-family: Arial,Helvetica,sans-serif;">Momentum (y): mv <span style="font-family: Arial,Helvetica,sans-serif;"> = 8255*3.53 <span style="font-family: Arial,Helvetica,sans-serif;"> = 29,140.15 kg*m/s <span style="font-family: Arial,Helvetica,sans-serif;">Kinetic Energy (y): KE = 1/2mv^2 <span style="font-family: Arial,Helvetica,sans-serif;"> = ½*8255*3.53^2 <span style="font-family: Arial,Helvetica,sans-serif;"> = 51,432.36 J

<span style="font-family: Arial,Helvetica,sans-serif;">The data for the Sidewinder is not accurate because the meter was set to scale in the foreground, but the data points were plotted in the distant background of the video; therefore, the scaling is offset. Nonetheless, the collected data should be proportional to the actual results, so if one can find the right proportions, of foreground measurement to background measurement, the collected data can be scaled to the correct magnitudes.
