Calculating Friction Using Coeffcients

Two blocks A ...

Question

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 $t_{A}$ and Block B hit wall in time $t_{B}$ . Assume the surface as frictionless, then.
