K.C.S.E Physics Q & A - MODEL 2013PP1QN16
​ (a) A horizontal force of 12 N is applied on a wooden block of mass 2 kg placed on a horizontal surface. It causes the block to accelerate at 5 m/s2. Determine the frictional force between the block and the surface. (3 marks)
(b) Figure 9 shows a graph of velocity against time for a ball bearing released at the surface of viscous liquid.
​Explain the motion of the ball bearing for parts
(I) OA (ii) AB (c) Figure 10 shows a pulley system used to raise a load by applying an effort of 500 N.
​State the:
(i) velocity ratio of the system. (ii) purpose of pulley 2. (iii) Given that the machine has an efficiency of 80%, determine the maximum load that can be raised.
