Using the concept of acceleration, explain how a swimmer can have a better time for a 100-m race in a 25-m pool than in a 100-m pool.
Homework Answers
For 100m race in a 25m pool, there are 3 changes in directions(So that that threre are 4 laps. SO total distance = 4*25 = 100m). When reached at the other end of the pool, the person can push himself and give himself a force so that he gets some acceleration. Due to the resistance the water some of the energy goes waste. So, it is difficult to get the same level of effectiveness if the person tries it in 100m pool(with just 1 lap and thus no force to help him to save some extra time)

This program will determine the finals time for a swimmer completing the 100 yard freestyle race The data file consists of the initials of the swimmer followed by the 4 "split" times in seconds. A 100-yard freestyle race is broken in to 4 25-yard lengths (AKA "splits"). Your program will: read the initials of the swimmers read the 4 split times -- the split times are in seconds compute the total of all 4 splits display the initials of the...

Choose a function to represent the acceleration vs. time graph. How can you calculate the values of the constants of this function from the function representing the position versus time graph? Check how well this works. You can also estimate the values of the constants from the graph. What kinematics quantities do these constants represent? Record the corresponding kinematic quantities and the values of the corresponding errors. From either the position vs. time, velocity vs. time, or acceleration vs. time...

The acceleration of a race car for the first few seconds of the race can be approximated by the a(t) = A + Bt linear formula, where t is the time measured in seconds and the values of the constants A and B are: A = 16.0 m/s2 and B = -2.00 m/s3. What is the speed of the car 2.30 s after it starts from rest? How much distance does the car cover during this 2.30 s time period?
