A supertanker of mass 4 x 10° kg is steaming at a constant speed of 8ms1.The resistance force is 2 x 10 N. What power are the ship's engines producing? One of the ship's two engines suddenly fails but the other continues to (i) work at the same rate. (ii) Find the deceleration of the ship immediately after the failure. The resistance force is directly proportional to the speed of the ship. liii) Find the eventual steady speed of the ship under one engine only, assuming that the single engine maintains constant power output.
