90. A unit, mounted on the end of the section, is thrown inextensible thread, the ends of which are attached to the loads, one of which (m1 = 400 g) is moving but the table surface, and the other (m2 = 600 g) - along the vertically downwards. The coefficient of friction f load on the table is 0.1. Considering the thread and block weightless, determine: 1) the acceleration a, which move goods; 2) the tensile force T of the thread.
