Physics Question about a bathysphere?

A bathysphere used for deep-sea exploration has a radius of 1.52 m and a m of 1.20 104 kg. To dive, this submarine takes on m in the form of sea water. Determine the amount of m that the submarine must take on if it is to descend at a constant speed of 1.10 m/s, when the resistive force on it is 1102 N in the upward direction. The density of seawater is 1.03 103 kg/m3.
