A supertanker with the mass of 1.72 *10^8 kg is moving with a constant velocity. Its engines generate a forward thrust of 5.52*10^4 N. Determine (a) the 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.
I honestly don't know how to do this at all but from the given infor. I thought I could find the sum of forces by M *A but then since it's constant velocity, A would be zero making sume of forces 0. Since it is constant velocity I thought i could use the constant velocity formulas but wasnt sure which one to use since I'm only give mass. I don't even know what kind of force a forward thrust would be considered as... I am so lost please help!
