You must have: Total Marks
Mathematical Formulae and Statistical Tables (Yellow), calculator
Candidates may use any calculator permitted by Pearson regulations. Calculators must not
have the facility for symbolic algebra manipulation, differentiation and integration, or have
retrievable mathematical formulae stored in them.
Instructions
•• Use black ink or ball-point pen.
•
If pencil is used for diagrams/sketches/graphs it must be dark (HB or B).
Fill in the boxes at the top of this page with your name,
••
centre number and candidate number.
Answer all questions and ensure that your answers to parts of questions are clearly labelled.
Answer the questions in the spaces provided
•
– there may be more space than you need.
You should show sufficient working to make your methods clear. Answers without working may
•
not gain full credit.
Whenever a numerical value of g is required, take g = 9.8 m s–2, and give your answer to either two
significant figures or three significant figures.
Information
•• A booklet ‘Mathematical Formulae and Statistical Tables’ is provided.
•
There are 7 questions in this question paper. The total mark for this paper is 75.
The marks for each question are shown in brackets
– use this as a guide as to how much time to spend on each question.
Advice
•• Read each question carefully before you start to answer it.

A light elastic spring has natural length l and modulus of elasticity λ
One end of the spring is attached to a point A on a smooth plane.

A particle P of mass m is attached to the other end of the spring.
Initially P is held at the point B on the plane, where AB is a line of greatest slope of
the plane.
The point B is lower than A and AB = 2l, as shown in Figure 1.
The particle is released from rest at B and first comes to instantaneous rest at the point
C on AB, where AC = 0.7l
