Secretariat ran the Kentucky Derby with times of 25.4 s, 24.3 s, 23.1 s, and 22.8 s, for the quarter mile.

(a) Find his average speed during each quarter-mile segment.

first segment -------- ft/s

second segment -------- ft/s

third segment -------- ft/s

fourth segment -------- ft/s

(b) Assuming that Secretariat's instantaneous speed at the finish line was the same as his average speed during the final quarter mile, find his average acceleration for the entire race. (Hint: Recall that horses in the Derby start from rest.)

------- ft/s2
