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. There are 18 printed pages.

2 Multiple Choice Questions [40 Marks] Shade your answers in the OTAS sheet provided. 1 A pair of vernier calipers is used to measure the thickness of 100 sheets of paper. The zero error and the measured thickness of the 100 sheets (in centimetres) are as shown in Fig. 1.1 and Fig. 1.2 respectively. Fig. 1.1 Fig. 1.2 What is the actual thickness of 1 sheet of the paper? A 1.02 x 10-2 cm B 1.03 x 10-2 cm C 1.04 x 10-2 cm D 1.02 x 100 cm 2 Which of the following consists entirely of scalar quantities? A power, energy and time B weight, length and speed C acceleration, force and velocity D speed, displacement and mass

3 3 The figure below shows a stroboscopic (an instrument similar to ticker tape) photograph of a ball rolling down a slope. The stroboscope is flashing at a period of 0.10 s. What is the acceleration of the ball? A 30 cm s-2 B 80 cm s-2 C 200 cm s-2 D 300 cm s-2 4 A car undergoes uniform deceleration along a straight road. It travels a distance of 100 m when it slows down from 35 m s -1 to 15 m s -1. How much longer will the car travel to come to a stop? A 3.0 s B 4.0 s C 5.7 s D 7.0 s

4 5 An E-scooter accelerates from rest for 3.0 s and then maintains a constant speed till it reaches its destination at t = 10.0 s. Which diagram shows the correct motion? A B C D 6 A hammer and feather are both released from rest at the same height and at the same time. Assuming air resistance is negligible, which statement below is true? A The gravitational forces acting on them are equal. B They have the same gravitational potential energy at the point of release. C They reach the ground with the same speed. D The acceleration of the hammer is higher than that of the feather. displacement / m time / s displacement / m displacement / m displacement / m time / s time / s time / s 0 3.0 10.0 0 3.0 10.0 0 3.0 10.0 0 3.0 10.0
