Maths On Track: Assessment Task
Name:
Date of Task:
Duration of Task: from 5 x 50 minute periods of class time
Time allocated: (250 minutes) in class under examination conditions.
Instructions
This SAC (school assessed coursework) is a problem solving task in which you are
required to make practical application of the theory, primarily from the rates of
change area of study, although some theory from other areas of study may be
required. You must answer all questions.
You should use your graphics calculator and you must clearly indicate how that
technology was used. Evidence for this maybe provided either in written form
(screen dumps for example), or through verbal communication with your teacher
who can observe your appropriate use of technology. It is your responsibility to
provide clear evidence of appropriate use of technology.
You may take into the SAC:
1) Your text book, 2) your summary book, 3) your graphics calculator.
Marks will not be given for the answers alone. In some cases you will need to
discuss the results you get, explaining both your reasoning and your working out.
This questions section of this paper has been printed single sided to
give you extra working space for each question (if needed).
Preparation for this SAC
On the following pages you have been provided with maps of the Australian Grand
Prix Albert Park circuit. Each of these maps provides you with different information
about the circuit, including layout and scale. You will need to refer to this information
to answer the questions in this SAC.
Before the SAC it will be useful for you to:
1. Identifying the relative speeds of each turn (which is slowest, fastest etc.)
2. Calculate the approximate distances between turns using the scale given on the
second map.
3. Use the following background information and maps to familiarise yourself with
the Grand Prix Circuit.
Complete all questions. Show all working out. Describe your use of technology

Background Information
Below is the layout of the Australian Grand Prix, Albert Park Circuit. The track
consists of 16 turns of varying difficulty for the driver. There are also straight
stretches along which very high speeds can be attained.
The circuit is 5303 metres in length. The Lap Record is held by Michael Schumacher
who, in 2004 completed one lap in 1:24.125 (1 minute 24.125 seconds) in his Ferrari,
with a top speed of 325 km hr
(http://www.formula1.com/races/in_detail/australia_787/). The Grand Prix runs for 58
laps totalling 307.574 km.

(not the first or last lap)?
b)
Rate turns 1 to 16 from fastest to slowest. Justify your ordering.
c)
What is the fastest section of the track? Why? Estimate the average speed of this
section.

2. a) Following a series of speed trials, the following speed-time graph was generated
representing one lap of the track. Mark on the graph the turns represented.
b) Construct you own speed (in km/hr) – time (in seconds) graph for the track
assuming constant acceleration between the turns.

i) t = 25
ii) t = 40
b) Calculate the area under your graph in 2 b). What does this area represent? Use
your calculation to comment on the accuracy of your velocity-time graph.

4. a) One of the most action packed sections of the circuit is the Jones chicane
located at turn one (a chicane is an S-shaped bend in a road used to slow
traffic). Using a map you have found in your research, and the data in the table
below, determine the deceleration at the Jones chicane given that the brakes
are applied for only 1.7 seconds.
