Write in dark blue or black pen. You may use a soft pencil for any diagrams or graphs. Do not use highlighters, correction fluid or correction tape. Section A Answer all questions. Section B Section B consist of two questions. Answer only one out of these two questions. Students are reminded that all quantitative answers should include appropriate units. The use of approved scientific calculator is expected, where appropriate. Candidates are advised to show all their working in a clear and orderly manner, as more marks are awarded for sound use of Physics than for correct answers. The number of marks is given in brackets [ ] at the end of each question or part question. This document consists of 22 printed pages.

2 Section A Answer all questions. 1 A remote drone of mass 5.0 kg is launched from the surface of a planet. Fig. 1.1 shows how the velocity of the drone varies with time until it lands back on the surface. After 1.7 s, the drone malfunctions and experiences a free fall. Fig. 1.1 (not to scale) (a) Explain how Fig. 1.1, from 1.7 s onwards, shows that air resistance on the drone is insignificant. …………………...…………………………………………………….…………….……. …………………...…………………………………………………………………..……. …………………...………………………………………………………………………[1] (b) Describe, in terms of velocity, the motion of the drone from 1.7 s to 9.0 s. …………………...…………………………………………………….…………….……. …………………...…………………………………………………………………..……. …………………...…………………………………………………….…………….……. …………………...…………………………………………………………………..……. …………………...…………………………………………………………………..….[3] 1.0 5.0 4.0 3.0 2.0 9.0 8.0 7.0 6.0 10.0 0 2 - 2 6 4 - 8 - 4 - 6 6.6 1.7 velocity m/s time / s
