How Does Weight Influence Net Force on a Submarine?

[jehan4141]

A 1450 kg submarine rises straight up toward the surface. Seawater exerts both an upward buoyant force of 16,140 N on the submarine and a downward resistive force of 1030 N.My question: Is the weight of the submarine included in the net force? If the weight is taken into account, is it included in the restive force? If weight is not included in the net force, why not?

Yes the weight would be included in the net force. The resistive force is due to the friction between the water and the submarine.
