Answer:
Swimmer A has reduced friction
tight kick with pointed toes reduces friction
Also, keeping your legs as tight together as possible helps to reduce friction because it streamlines, or compresses, the legs. And pitting he head down helps to reduce friction.
Keeping the head down helps keep it in alignment with the body, but more importantly, a head down also can help reduce surface or wave drag. There is actually less drag underwater than on the surface of the water (think of a submarine), because we eliminate surface drag.
A would win the race!
In simple terms, friction makes it hard to slide through water, forcing swimmers to expend more energy to achieve higher speeds. ... Maintaining high energy levels helps swimmers move faster and for longer; even a fraction of a second might make the difference between winning and losing a competition.
