Asked by Anji

I have no idea how to start this problem. I don't want the answer just how to start.A supertanker (mass = 1.70x10^8kg) is moving with a constant velocity. Its engines genterate a forward thrust of 7.40x10^5N. Determine (a) magnitude of the resistive force exerted on the tanker by the water and (b) the magnitude of the upward buoyant force exerted on the tanker by the water.

A supertanker (mass = 1.57E+8 kg) is moving with a constant velocity. Its engines generate a forward thrust of 7.47E+5 N. Determine the magnitude of the resistive force exerted on the tanker by the water.

7.47×10^5 N is correct, but i need to know how
