3. A 3 kg salmon swims in still open water with a speed of 0.6 m/s. A Using Lecture 17 (slide 8), estimate the drag force in newtons on the fish while swimming at this speed, and the mechanical power in watts that the fish has to provide. B If the swimming speed is limited by the muscle power, estimate the maximum swimming speed for this fish. max muscle power = 200 W/kg C The fish now swims upstream against a current with a speed of 0.67 m/s. The fish makes slow progress of 0.33 m/s relative to the ground. What mechanical power must the fish provide to swim in these conditions? And how many joules of work must the fish do to swim upstream by 1 meter, as measured on the ground? a. From slide 8, every cost 1.3 M -0.27 1.3 (3) -0.27 = 0.9665/m/kg dry form=
