An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship. when the craft was stationary, the tension in the cable was 6000 n. when the craft was lowered or raised at a steady rate, the motion through the water added an 1800 n drag force. a. what was the tension in the cable when the craft was being lowered to the seafloor?
b. what was the tension in the cable when the craft was being raised from the seafloor?
