Could someone show me the steps, I want to learn how to solve this question! A spherical vessel used for deep-sea exploration has a radius of 1.51 m and a mass of 1.21 104 kg. To dive, the vessel takes on mass in the form of sea water. Determine the amount of mass that the vessel must take on if it is to descend at a constant speed of 1.40 m/s, when the resistive force on it is 1105 N in the upward direction. The density of seawater is 1.03 103 kg/m3.

That's a lot of calculation I can't do right now(doing homework) but it involves the buoyant force. Sketching the info you have should help. Sorry I can't help more.
