The world record for the 100m freestyle is 46.91s. The 100m is achieved by swimming the full length of a 50m pool and returning. Assuming a time of 20.91s for the first 50m, what is the average velocity for the second leg?
The world record for the 100m freestyle is 46.91s. The 100m is achieved by swimming the full length of a 50m pool and returning. Assuming a time of 20.91s for the first 50m, what is the average velocity for the second leg?
Final answer:Theaverage velocityfor the second leg of the 100m freestyle is 1.92 m/s.Explanation:To find the average velocity for the second leg, we need to determine the time it takes for the swimmer to complete the second 50m. We know the total time for the 100m is 46.91s, and the time for the first 50m is 20.91s. So, the time for the second 50m can be found by subtracting the time for the first 50m from the total time: 46.91s - 20.91s = 26s.Now, we can calculate the average velocity for the second leg by dividing the distance (50m) by the time (26s). So, the average velocity for the second leg is: 50m / 26s = 1.92 m/s.Therefore, the average velocity for the second leg of the 100m freestyle is 1.92 m/s.Learn more about Average velocity here:brainly.com/question/1375440#SPJ11...
