Figure Q2 (b)
Figure Q2 (b) shows a box fitted with a pulley. The wall has one pulley fixed. A cord is pulled with a tension, T, is attached to the centre of the pulley of the box and wrapped around the pulleys. Given T=3XN and the mass of the block, m=1Xkg where X is the last non-zero digit of your Matric number. For example: if your matric number is AN201050, then T=35 N and m=15 kg. (i) Draw the free body diagram and kinetic diagram. (2 marks) (ii) Determine the maximum frictional force. (3 marks) (iii) Determine the total force in the x-direction, Fx, due to the tension on the cord and due to the pulleys. (3 marks) (iv) Explain if the box will move or not. (2 marks) (v) Determine the acceleration of the box. (3 marks) Figure Q2 (c) shows an impact event. A big disc, ml=8 kg impacts a smaller disc, m2 =Xkg where X is the last non-zero digit of your Matric number. For example: if your matric number is AN201050, m2=5 kg. The initial velocities of the discs are given in Figure Q2 (c) and the coefficient of restitution e=0.80. Calculate the magnitude and directions of the final velocities of m1 and m2.
