# Pulleys+Impusle+Acceleartion!

Classical Mechanics Level 4

Two blocks $$A$$ and $$B$$ of same mass $$M$$ are connected with each other with an ideal string of length $$2l$$ passing over an ideal pulley. The block $$A$$ is connected to a light pan $$C$$ with an ideal string as shown in figure. A particle of mass $$\frac{M}{2}$$ is dropped on pan from height $$\frac{l}{2}$$ as shown. If collision between particle and pan is plastic, acceleration of $$B$$ just after the collision is?
