46)In the 2016 Olympics in Rio, after the 50 m freestyle competition, a problem with the pool was found. In lane 1 there was a gentle 1.2cm/s current flowing in the direction that the swimmers were going, while in lane 8 there was a current of the same speed but opposite to the direction of the swimmers'. Suppose a swimmer could swim the 50 m in 25.0 seconds in the absence of any current. What would be her time in lane 1? In lane 8? How does the difference in these times compare to the actual 0.06 difference in times between the gold medal winner and the fourth-place finisher? Knight College Physics 4th Chapter 3 Question 46
