Physics Help!!An early submersible craft for deep-sea exploration was raised and lowered by a cable from a ship.?

An early submersible craft designed 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 measured at 7500 N. However, when the craft was either lowered or raised at a steady rate, it experienced an additional drag force of 1800 N due to its motion through the water.

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?
