The A kg collar is initially at rest on the bar at position 1 as shown in Figure Q2. The coefficient of friction between collar and the bar is given as u = 0.1. The collar is subjected to a constant force P = 50 N horizontally. The spring has a constant k = 150 N/m and is held by cables so that it is initially compressed B cm. Suppose the spring will be compressed 100 mm further when the collar hit the spring at position 2. Here, the value of A and B depends on the 5th and 6th digit of your matric number respectively as shown in Table 1. For example, if your matric number is DD 170150 gives the value of A = 5 kg and B = 10 cm.
