PART A AND C ONLY SOLVE CAREFULLY!! Please Write Clearly and Box the final Answer(s) Use THE CORRECT UNITS) Express your answer to three significant figures and include appropriate units. DRAW THE FREE BODY DIAGRAM and label it for this problem as well


Extracted text: The elastic cord has an unstretched length ln = 1.5 ft and a stiffness k = 12 lb/ft. It is attached to a fixed point at A and a block at B, which has a weight of W = 2.8 lb. The block is released from rest from the position shown. After leaving the guide, it is launched onto the smooth horizontal plane. (Figure 1) Part A Determine its speed when it reaches point C after it slides along the smooth guide. Express your answer to three significant figures and include the appropriate units. HA ? vC = Value Units Submit Request Answer Part B Will the angular momentum of the block about point A be conserved after it passes point C? Yes O No Submit Previous Answers v Correct Figure 1 of 1> Part C 4 ft Calculate the magnitude of the angular momentum of the block about point A, at any instant after it passes point C. Express your answer using three significant figures. 3 ft k = 12 lb/ft vec ? HA = slug · ft? /s Submit Request Answer D Pearson
