You place a 3.0-m-long board symmetrically across a 0.5-m-wide chair to seat three physics students at a party at your house. If 70-kg Dan sits on the left end of the board and 50-kg Tahreen on the right end of the board, where should 54-kg Komila sit to keep the board stable? Ignore the mass of the board and treat each student as point-like objects. The positive x-direction is to the right, and the origin is at the center of the chair. Part A Determine the coordinate of the leftmost point on the board where Komila can sit to keep the board stable. Express your answer with the appropriate units. x1 = nothing nothing Request Answer Part B
