Acertain sprinter has a top speed of 10.6 m/s. if the sprinter starts from rest and accelerates at a constant rate, he is able to reach his top speed in a distance of 11.9 m. he is then able to maintain his top speed for the remainder of a 100 m race. (a) what is his time for the 100 m race? (b) in order to improve his time, the sprinter tries to decrease the distance required for him to reach his top speed. what must this distance be if he is to achieve a time of 10.4 s for the race?
