Fig. 9.1 shows a large container ship travelling at constant speed in a straight line. Fig. 9.1 The resistive force acting on the ship is 2.8 x 106N. (a) The speed of the ship is 9.7m/s. (1) Calculate the work done against the resistive force on the ship in 1.0s. work done = [2] [2 (iThe engines are powered by oil. State the energy transfer that is taking place when the ship is travelling at constant speed. [2] (b) The mass of the ship is 2.2 x 10kg. The engines are switched off and the resistive force causes the ship to decelerate. (Calculate the initial deceleration of the ship. deceleration = [2]
