4 An iceberg is а lаrge piece оf freshwаter ice that has brоken оff a glacier or an ice shelf. Some scientists believe that icebergs could be used to supply freshwater. It has been estimated that an iceberg of mass 3.0 × 109 kg could provide water for half a million people for up to a year. Computer models have calculated that just one tug boat would be needed to move such an iceberg half way around the world. (a) Draw and label a free-body force diagram showing all the forces acting on the iceberg. (4) (b) The iceberg is moving at a constant speed and the tensions in the two tow ropes are equal. Show that the tension in each rope is about 2 × 105 N. drag force from the water = 3.3 × 105 N (3) (c) Calculate the work done by the tug boat on the iceberg when the iceberg is pulled through 50 km. (3) (d) State and explain the effect on the motion of the iceberg if the tow ropes were longer. Assume that the tug boat’s power output remains the same. (2) (e) The tug boat is moving through the water due west at 2.6 km hour–1. There is a water current of 0.9 km hour–1 due south Draw a vector diagram to scale, to determine the magnitude and direction of the resultant velocity of the tug boat.
