At time t1 is the speed of cadet B greater than, less than, or equal to the speed of cadet A? b. At time t2, is cadet B speeding up, slowing down, or moving with constant speed? c. From time t = 0 to time t = 60 s, is the average speed of cadet B greater than, less than, or equal to the average speed of cadet A? Explain.
