A swimmer covers the 50-yard freestyle in a time of 0:2805 (28.05 sec), measured by electronic timer pads The double length of the pool measures as s . 50.0 ± 0.5 yards. The time can be taken as t 28.05 ±0.01 sec. The resulting speed, according to ves/t, Is then 1.78 yards/s Which of the following would be an acceptable way to give the uncertainty of the speed v? 0 Δu=0.5prd/s since the distance has the larger uncertainty. 。Aw =...
