1. Say a bus is at a particular point X. It travels to Point Y. Briefly state ONLY the required values in order to get a value of the gain/loss in G.P.E. as the bus travels from Point X to Point Y. [4 marks]
2. In your opinion, are advertisements on buses, even those that obscure vision, more of an advantage or disadvantage? [4 marks]
3. Suggest reasons for the following. Support your answers.
a) TITO promotion [1 mark]
b) Overnight Parking [1 mark]
4. a) State a chemical that can be used for catalytic catalysts. [1 mark]
b) Why are catalytic converters important? [4 marks]
c) In your opinion, do you think the maintenance of catalytic converters is more important than that of the ability of the bus to showcase "impressive abilities"? (impressive abilities is up to the candidate's understanding and comprehension of the term.) [5 marks]
Section B: Long-Answer Questions.
5. a) To what extent is our transportation system successful in terms of efficiency? Explain your answer. [12 marks]
b) "SBS Transit's efforts are more of a success than a failure from 2006 - 2007." Do you agree? Explain your answer. [13 marks]
6. Suggest an experiment to determine if a bus is speeding, in S.I. units. (The S.I. unit of length is the metre and the unit of time is the second.)
A track is provided for you, which is 4km long, and has markings of 500m from the origin, O, of the track. The vehicle driver is known to be able to drive very steadily (straight).
In your experimental outline, state the materials required, procedues to be done, and any other required information. [15 marks]
NOTE: These questions are meant just for thinking purposes. No intention to criticise anyone's ideas, or perceptions. For questions 2, 4c, 5a and 5b, no definite answer is required. However, the ability to debate will certainly pay off. A basic bus knowledge is required in tackling these questions, which also means one should have understanding in certain scientific concepts, company policies and practical skills in appreciating the transportation system, strengths and weaknesses of it, and certain events that affected the system. (for e.g. the NEL Rationalisation, or the Old Airport Road diversion due to CCL.)
