Extracted text: 3 A ship sails in sea-water (p = 1024 kg / m ) at a velocity of 25 m / s. A 1:10 model is sailing in water of %3D 3 density = 1000 kg / m . Find the speed and resistance due to waves on model, if the resistance due to waves on prototype is 430 N. 1. V = 6.21 m / s, F = 0.36 N %3D V = 7.90 m / s, F = 0.36 N V = 7.90 m / s, F = 0.42 N 4. V = 6.21 m / s, F = 0.42 N 2. 3.
