Write in dark blue or black pen. You may use a soft pencil for any diagrams, graphs or rough working. Do not use staples, paper clips, glue or correction fluid. Section A Answer all questions. Write your answers in the spaces provided. Section B Answer one question. Write your answers in the spaces provided. Candidates are reminded that all quantitative answers should include appropriate units. The use of an 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. At the end of the examination, submit this question paper.

2 BSS/24/Preliminary Examination/4E Physics SECTION A Answer all questions. 1 An aircraft flies at a constant height. The force from the aircraft’s engines produces a force on the aircraft of 36 kN due north, as shown in Fig. 1.1. The wind produces a force of 12 kN towards the east. Fig. 1.1 (not to scale) Draw a scale drawing to show the resultant force acting on the aircraft. Use your drawing to determine the magnitude and direction of the resultant force. scale: ................................................. size of resultant force = .................................................. direction = .............................................
