Asked by Diaco
A spherical vessel used for deep-sea exploration has a radius of 1.50 m and a mass of 1.20 Γ 104 kg. To dive, the vessel takes on mass in the form of seawater. Determine the mass the vessel must take on if it is to descend at a constant speed of 1.20 m/s, when the resistive force on it is 1100 N in the upward direction. The density of seawater is equal to 1.03 Γ 103 kg/m3.

Where π is the mass of the added water and π£ is the sphereβs volume. 1.20Γ104ππ+π=1.03Γ103[43π(1.50)3]+1100π9.8π/π 2=2.67Γ103ππ
