What kind of mechanical work must make a swimmer to overcome the drag force of water at the final interval length of 25 meters, moving at a constant speed according to the schedule of master of sports (200 meters in 1 minute 56 seconds.)? What if he is to develop mechanical power motion if the water density of 10 ^ 3 kg / m ^ 3? Factor streamlining 0.7. Middle section of the body of the swimmer 0.1 m ^ 3, the angle of attack of 25 degrees swimmer.

Detailed solution shorthand terms, formulas, laws used in the decision, the withdrawal of the calculation formula and the response.
