a) b) C) For each skater, use computer software (ex. Excel) to calculate the average speed (m/s) and average acceleration (m/sz) for each of the 400m intervals using the split time information provided (show/explain the equations used and report your raw data). Then create two plots; the average speed vs distance (i.e. plot the average speed for each 400m interval) and the average acceleration vs distance (i.e. plot the average acceleration for each interval based on how the velocity changed with each interval). For comparison purposes, include the data from all three skaters on each plot. Adjust the scales of the y-axes of your graphs so it is easier to see appropriate trends in the data. For the acceleration graph, you can ignore the high acceleration in the first interval and adjust the y-axis so you can more easily see the trends for the rest of the race (focus on this for your analysis). Based on your data, in which 400m interval did each of the skaters reach their peak speed? Calculate each skater's average speed for the whole race (i.e. total distance divided by the total time). Calculate each skater's average speed for the last 1200m of the race (use the data from the split times at 3800m and SOOOm). Please show your work and equations used
