This Question Paper consists of 16 printed pages including the cover page. [Turn Over INSTRUCTIONS TO CANDIDATES Write your name, class and register number in the spaces provided. Write in dark blue or black ink. For Section A, indicate your answers on the separate Answer Sheet provided. Answer all other questions in the spaces provided. All quantitative answers should include appropriate units. You are advised to show all your working in a clear and orderly manner, as more marks are awarded for sound use of Physics than for correct answers. INFORMATION FOR CANDIDATES Assume g = 9.81 N kg-1 unless stated otherwise. The number of marks is given in brackets [ ] at the end of each question or part question. You may be penalised for incorrect use of units and/or not giving quantitative answers to an appropriate number of significant figures. The total number of marks for this paper is 80 and the weighting is 40%.
