The 10kg 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 10 cm. Suppose the spring will be compressed 100mm further when the collar hit the spring at position 2. Table 1 (a) Sketch the free body diagram of collar at position 1. (b) Determine the friction force impose to the collar. (c) Analyze the velocity of collar at position 2.
