Racer A, Racer B, and Racer C are in a marathon. Supposed time stopped for a while (players not moving like they have been frozen in time) and once the time resumes, the racers must run along a 16-m path to the finish line within 4 seconds. The motion of each racer while they are still moving (before the time stopped and they stopped moving) is as follows: 7 Racer A runs at aa = (1.5s¯8) m/s² where s is in meter. 8 Racer B runs at v8 = (1.2t3) m/s but he only started running after 1.5 s. Racer C runs at ac = 2 m/s² for 2.5 seconds and maintains his speed af- terwards. a.) Who will reach the finish line? b.) In what order will they reach the finish line if the time limit is ne- glected?
