What is plagiarism
Plagiarism is when you copy someone else’s answers. Even if you make slight changes in sy
mbols it is
still plagiarism. Plagiarism is cheating and is wrong. If it is detected all the people whose answers are
extremely similar will get zero marks for the questio
ns involved.
It is a good idea to discuss problems with other people.

Assignment
QUESTION 1

30 marks
As a student at QIBT, you travel trough the various Griffith University campuses most
ets lost easily around the campus, your job is to
provide him/her
with
a vector map to
at least three
locations in one of the Griffith University campuses.
You may find the campuses maps at

griffith/campuses/campus

maps
Your vector map must include: • Starting point and destination for each vector • Each
vector (shown as arrows) on the path • Scale and orientation • Calculated total distance
to each location
(scalar) • Calculated total displacement (vector) with its magnitude and
directio
n.
You will provide an accurate scale drawing of the various
vectors
along with the
mathematical calculations required.
You will have the opportunity to
discuss
your
drawing
s
and
calculations
with
your
tuto
r before
final submission
during consultations
.
however, you must reference all the resource
s used in your reference page, a

QUESTION 2

10 marks
What is the purpose of adding vector
s both graphically and numerically?
List several scalar quantities. Explain the differences between scalar and vector
quantities.
Besides adding vectors, we can also subtract vectors by our two graphical techniques.
Explain and demonstrate how
subtraction
can be done using both
graphical
techniques.
QUESTION 3

10 marks
Three family portraits of equal weight (15 Newtons) are hung by wires at different
angles, see pictures below. Explain which wires of which portrait are less likely to break
and why. Give
a full mathematical reasoning behind your explanation. Saying this or
that portrait will not get you any marks.
QUESTION 4

i
) What is the sum of these three vectors?
ii
) If these vectors represent forces on an object, what does this imply about the object?
