Oceanographers use submerged sonar systems, towed by a cable from a ship, to map the ocean floor. 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 1.3m2 , a drag coeffecient of 1.2, and when towed at 4.3 m/s, the tow cable makes an angle of 30 degrees with the horizontal. what is the tension in the cable? take the water density to be 1000 kg / m3
