Question 7 The ropes in the FIGURE 6 below are each wrapped around a cylinder, and the two cylinders are fastened together. The smaller cylinder has a diameter of 10 cm and a mass of 3.0 kg; the larger cylinder has a diameter of 20 cm and a mass of 15 kg. The ends of the ropes are connected to 2.5 kg and 4.0 kg respectively. Calculate the angular acceleration of the cylinders? Assume that the cylinders turn on a frictionless axle. 2.5 kg Figure 6 Question 8 8.1 In FIGURE 7, block B is falling and dragging block A across a table. 8.1.1 How many force vectors would be shown on a free-body diagram of block A? Name them. 8.1.2 Draw a labelled free- body diagram for the forces acting on block B. A 4.0 kg B [10] 8.2.1 Which object has the largest mass? Explain. 8.2.2 Which object has the smallest mass? 8.2.3 What is the ratio of the mass of object A to that of object B? (5) (2) Figure 7 8.2 A constant force applied to object A causes it to accelerate at 4 m/s². The same force applied to object B causes an acceleration of 8 m/s². When applied to object C, the rate of acceleration is 6 m/s². (1) (2) (2) [12]
