Two blocks A and B , each of same mass m 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) . Block B will swing and hit the surface in time t(b).
Assume the surface as frictionless.
Then prove that ,
The Attempt at a Solution
Let the tension in the string be T .
How to get the time t(b) .
