Tabletop with hole B. A string comes out with an attached mass. The particle is traveling around with an angular velocity θ ˙ . Figure by MIT OCW. Assume: Frictionless surface. Inextensible String. Pull string through hole at B such that: dr r ( t 0 ) = L dt ( t 0 ) = 0 r ( t 1 ) = L/ 2 dr ( t 1 ) = 0 dt If θ ˙ ( t 0 ) = θ ˙ 0 , what is θ ˙ ( t 1 ) = θ ˙ 1 ?
