Do not open this booklet until you are told to do so. INFORMATION FOR STUDENTS There are forty questions on this paper. Answer all questions. For each question there are four possible answers A, B, C and D. Choose the one you consider correct and record your choice using 2B soft pencil to shade in the OTAS sheet provided. Calculators are allowed for this paper. Take g = 10 N/kg or 10 m s-2. There are 16 printed pages.

2 Multiple Choice Questions [40 Marks] 1. Which physical quantity listed below is a scalar quantity? A acceleration B force C mass D velocity 2. A student attempts to measure the period of oscillation of a pendulum in a laboratory which is located at 10 m above sea level. The average value of the period of oscillation is determined to be 1.6 s. He then repeats the same experiment from a height of 5 m above sea level, using a pendulum bob with half the mass but keeping the length of the pendulum constant. Which is the most likely value of the period of oscillation measured in the second attempt? A 0.4 s B 0.8 s C 1.6 s D 3.2 s 3. A student determines the circumference of a golf ball. Which instrument directly measures the circumference of the golf ball? A calipers B micrometer C rule D tape 4. Paths are laid as shown between points X, Y and Z. A person walks along the paths from X to Y to Z and then back to X. What is the value of the total displacement and of the total distance travelled? total displacement / m total distance travelled / m A 0 0 B 0 24 C 24 0 D 24 24 X Y Z 6.0 m 8.0 m 10.0 m

3 5. A car travels along a road. The driver stops the car by pushing his foot down on the brake pedal. What does not change if he pushes harder on the brake pedal? A the braking distance B the braking force C the stopping distance D the thinking distance 6. An object is thrown vertically upwards from point A with an initial velocity. It travels to the highest point B and then falls back to A. Neglecting air resistance, which one of the following statements is incorrect? A The acceleration of the object is constant throughout the motion. B The time for the upward motion is longer than the time for the downward motion. C The total displacement of the object is zero. D The velocity of the object at the highest point is zero. 7. What is the size of the resultant of the two forces shown in the diagram? A 1.0 N B 3.5 N C 5.0 N D 7.0 N stopping distance braking distance thinking distance hazard detected braking begins the car stands still 4.0 N 3.0 N
