Constants Periodic Table A seesaw has a mass of 50 kg, a length of 3.0 m, and a fulcrum beneath its midpoint. It is balanced when a 60-kg person sits on one end and a 84-kg person sits on the other end Part A Find a displacement of the center of mass of the seesaw relatively to the fulcrum. Express your answer with the appropriate units. Enter negative value if the center of mass is located closer to the 60-kg person and positive value if the center of mass is located closer to the 84-kg person alue Units Submit Request Answer Part B Consider a system consisting of a uniform 3.0-m long seesaw that has a mass of 50 kg and two people of masses 60 kg and 84 kg sitting on its ends. Find a displacement of the center of mass of the system relatively to the seesaw's midpoint. Express your answer with the appropriate units. Enter negative value if the center of mass is located closer to the 60-kg person and positive value if the center of mass is located closer to the 84-kg person alue Units
