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 60-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.Determine the coordinate of the leftmost point on the board where Komila can sit to keep the board stable.
