A fixed pulley carries a weightless thread with masses `m_(1)` and `m_(2)` at its ends. There is friction between the thread and the pulley. It is such that the thread starts slipping when the ratio `m_(2)//m_(1)=eta_(0)` find :
(a) The friction coefficient
(b) The acceleration of the mass when `m_(2)//m_(1)=eta gt eta_(0)`

In the arrangement shown in fig the bodies have masses m_(0), m_(1) and m_(2) the friction is absent the masses of pulleys and the threads are negligible find the acceleration of the body m_(1)
