In attempting to maximize a swimmer's velocity through the water, at high velocities it would normally be MOST productive to have the swimmer:Question 6Select one:a.maintain his/her legs in a more horizontal alignment to maximize streamlining and thereby decrease form dragb.wear tighter fitting swimmers of hydro-dynamically designed material and shave any excess body hair to decrease surface dragc.minimise vertical movements of his/her body to decrease wave dragd.increase hydrodynamic lift by modifying his/her hand position and thereby increase propulsion through the watere.all of the suggestions would be equally productive in maximizing a swimmer's velocity through the water

A swimmer is towed through the water firstly while lying in a prone position on the water surface, then in a prone position but submerged under the water surface (assume the swimmer maintains the same horizontal position and is towed at the same speed in both situations). The person towing the swimmer would usually need to apply the greatest force to move the swimmer through the water in which situation:Question 17Answera.the prone position on the water surface and pulled quickly because, in this position, the swimmer has a higher wave drag than when submergedb.the prone position on the water surface because in this position, the swimmer has a higher surface area exposed to two types of fluid than when submerged, which increases form dragc.the submerged prone position and pulled quickly because, in this position, the swimmer has a less streamlined body position compared to when on the water surface, which increases form dragd.the submerged prone position and pulled quickly because, in this position, the swimmer has a higher surface area exposed to the flow compared to when on the water surface, which increases surface drage.the same force would be applied to the swimmer in a prone position on the water surface and when submerged to move them at the same velocity through the water. This is because there is the same amount of form drag in both situations.

The speed of a swimmer is 4 km h−14 km h-1 in still water. If the swimmer makes his strokes normal to the flow of river of width 1 km1 km, he reaches a point 750 m750 m down the stream on the opposite bank. The speed of the river water is

Case study 1Julie is a long distance swimmer for Victoria. Her favourite events are 800m and 3km freestyle. She trains 4 mornings a week and 4 afternoons a week. She is really focusing on maintaining the same speed for a long distance of time. Julie's aim is to get into the Olympics one day to represent her country. At this stage she is really struggling to get a good start and being able to increase her speed in the last 100m.List the 2 fitness components that are likely to be her best?*2 points

A person swims in a river aiming to reach exactly on the opposite point on the bank of a river. His speed of swimming is 0.5 m/s at an angle of 120∘ with the direction of flow of water. The speed of water is
