1. The problem statement, all variables and given/known data Two blocks A and B ,each of same mass are attached by a thin inextensible string through an ideal pulley.Initially block B is held in position as shown in figure.Now the block B is released .Block A will slide to right and hit the pulley in time t1. Block B will swing and hit the surface in time t2 . Assume the surface as frictionless,then which block will hit in lesser time i.e t1 or t2 ? Please explain mathematically?? 2. Relevant equations 3. The attempt at a solution Intuitively it looks block A will hit first.But mathematically I am not able to relate.Block A does a linear motion covering distance L.Block B doing a circular motion with varying radius(as it falls the initial radius length L will increase ? How to relate displacement , accelaration ?
