Solve the all parts of given problem:
Problem: 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 5500 N. When the craft was lowered or raised at a steady rate, the motion through the water added an 1800 N drag force.
Part I: What was the tension in the cable when the craft was being lowered to the seafloor?
Part II: What was the tension in the cable when the craft was being raised from the seafloor?
I need help to find the tension in the cable when the craft was being raised from the seafloor.
