A uniform metre stick of mass math xmlns=http://www.w3.org/1998/Math/MathMLmiM/mimo /mo/mathis hinged at one end and supported in a horizontal direction by a string attached to the other end. What should be the initial acceleration (in math xmlns=http://www.w3.org/1998/Math/MathML class=wrs_chemistrymirad/mimo//momsupmi mathvariant=normals/mimn2/mn/msup/math ) of the stick if the string is cut?
