Final answer:
The coach's new stopwatch will be helpful in timing the sprint team because its uncertainty falls within the range of times that the sprinters regularly clock.
Step-by-step explanation:
Yes, the coach's new stopwatch will be helpful in timing the sprint team. The stopwatch has an uncertainty of ±0.05 s, which falls within the range of times that the sprinters regularly clock. The first-place sprinter came in at 12.04 s and the second-place sprinter came in at 12.07 s, both of which are well within the stopwatch's range of accuracy.
