2 SECTION A Answer all the questions. 1 (a) Complete Table 1.1. Give the missing prefix, symbols and value. Table 1.1 prefix symbol value mega M 106 micro 10-6 10-9 tera [3] (b) Force is a vector quantity. State one other example of a vector quantity. ....................................................................................................................................... [1] (c) Fig. 1.1 shows an oil rig being towed by two tugs A and B. The rig is moving at constant speed. Fig. 1.1 Each tug exerts a force of 6000kN. oil rig tug A tug B 50°

3 (i) By drawing a vector diagram, determine the size of the resultant force on the rig due to the tugs. resultant force = ………………… [3] (ii) State the resistive force acting on the rig. resistive force = ………………… [1] [Total: 8]

4 2 A model rocket is launched vertically upwards from rest. The rocket reaches a velocity of 41m/s, at which the fuel is used up. Fig. 2.1 shows the velocity-time graph for the motion of the rocket from its launch until it returns to Earth. Fig. 2.1 (a) Draw a line to join each region on the graph to the description of the motion of the rocket in the region. region on the graph motion of rocket [2] (b) On Fig. 2.1, mark with a letter H, the point where the rocket reaches its highest point. [1] (c) Using Fig. 2.1, calculate the maximum height reached by the rocket.
