An automobile being reads 8.0 seconds and is 550 feet from the starting point when the stopwatch reads 10.0 seconds A. What was the average velocity of the automobile during the interval from t - 8.0 seconds to t 10.0 seconds? B. What was the average velocity of the automobile during the interval from t-0s to t- 10.0 s? (Assume that the stopwatch read t = 0 and started at the same time as the auto.) C. If the automobile averages 100 ft/s from t = 10.0 s to t = 20.0 s, what distance does it travel during this interval? D. The automobile has a special speedometer calibrated in feet/s instead of in miles/hour. At t -8s the speedometer reads 65 ft/s; and at t - 10 s it reads 80 ft/s. What is the average acceleration during this interval?
