Question

One swimmer in a relay race has a 0.50 s lead and is swimming at a constant speed of 5.00 m/s. The swimmer has 44.0 m to swim before reaching the end of the pool. A second swimmer moves in the same direction as the leader. What constant speed must the second swimmer have in order to catch up to the leader at the end of the pool?​

Answer 1

See below

Step-by-step explanation:

The lead swimmer will finish in 44 m / 5 m/s = 8.8 seconds

the second swimmer has to cover the 44 m PLUS the length he is behind

the first swimmer in the same amount of time

(44 m + 1/2 s * 5 m/s) / 8.8 s = 5.284 m/s
