Question

Oceanographers use submerged sonar systems, towed by a cable from a ship. In addition to their downward weight, there are buoyant forces and forces from the flowing water that allow them to travel in a horizontal path. One such submersible has a cross-section area of 1.6 m2, and, when towed at 4.6 m/s, the tow cable makes an angle of 35 degrees with the horizontal and has a tension of 24,025 N. What is the drag coeeficient of the submersible? (Assume that ρsea = 1030 kg/m3)
