1 hour 15 minutes
Candidates answer on the Question Paper.
No Additional Materials are required.
READ THESE INSTRUCTIONS FIRST
Write your Centre number, candidate number and name on all the work you hand in.
Write in dark blue or black pen.
You may use an HB pencil for any diagrams or graphs.
Do not use staples, paper clips, glue or correction fluid.
DO NOT WRITE IN ANY BARCODES.
Answer all questions.
Electronic calculators may be used.
You may lose marks if you do not show your working or if you do not use appropriate units.
Take the weight of 1.0 kg to be 10 N (acceleration of free fall = 10 m / s2).
At the end of the examination, fasten all your work securely together.
The number of marks is given in brackets [ ] at the end of each question or part question.

1 (a) Fig. 1.1 shows the axes of a distance-time graph for an object moving in a straight line.
Fig. 1.1
(i) 1. On Fig. 1.1, draw between time = 0 and time = 10 s, the graph for an object moving
with a constant speed of 5.0 m / s. Start your graph at distance = 0 m.
2. State the property of the graph that represents speed.
....................................................................................................................................
[2]
(ii) Between time = 10 s and time = 20 s the object accelerates. The speed at time = 20 s is
9.0 m / s.
Calculate the average acceleration between time = 10 s and time = 20 s.
acceleration = ...........................................................[2]

Fig. 1.2
(i) The object has an initial speed of 50 m / s and decelerates uniformly at 0.35 m / s2 for
100 s.
On Fig. 1.2, draw the graph to represent the motion of the object. [2]
(ii) Calculate the distance travelled by the object from time = 0 to time = 100 s.
