Do not use staples, paper clips, glue or correction fluid. Write your name, class and index number on the Question Paper and Answer Sheet in the spaces provided. There are forty questions in this paper. Answer all questions. For each question, there are four possible answers, A, B, C, D. Choose the one you consider correct and record your choice in soft pencil on the separate Answer Sheet. Read the instructions on the Answer Sheet very carefully. Each correct answer will score one mark. A mark will not be deducted for a wrong answer. Any rough working should be done in this booklet. The use of an approved scientific calculator is expected, where appropriate. Take g = 10 ms-2 or 10 Nkg-1 unless specified otherwise This question paper consists of 24 printed pages CANDIDATE NAME CLASS REGISTER NUMBER

2 1 Which pair consists of both vector quantities? A Force and power B Pressure and volume C Acceleration and weight D Density and kinetic energy 2 Four rectangular blocks, T, U, V and W are shown. Each block is labelled with its dimensions and mass. Which two blocks have the same density? A U and V B V and W C T and U D T and V

3 3 Forces of 40 N and 25 N act on an object in the directions shown. Which arrow shows the direction of the resultant force on the object?

4 4 A ball is dropped from the top of a ladder. It falls vertically through air and rebounds in a vertical path upon hitting the ground. Assuming that no energy is lost during its impact with the ground and that air resistance is negligible, which velocity-time graph best describes the motion of the ball? A B C D v / m / s t / s v / m / s t / s v / m / s t / s v / m / s t / s

5 5 A brick, initially at rest, falls from a height of h and took 2.0 s to reach the ground. The acceleration of free fall, g = 10 m/s2 . What is the height h of the brick? A 10 m B 20 m C 30 m D 40 m 6 A car is initially travelling along a straight path at 5.0 m/s. It then accelerates at 2.0 m/s2 for 10 s. What is the final speed of the car? A 5.0 m/s B 10 m/s C 20 m/s D 25 m/s

6 7 A 10 kg mass is initially at rest on a rough horizontal surface. A horizontal force is then applied to it and the force applied varies according to the diagram shown. Given that the frictional force acting on the mass when it is moving is 1 N,
