Find the acceleration of the body of mass `m_(2)` in the arrangement shown in figure. If the mass `m_(2)` is `eta` times great as the mass `m_(1)` and the angle that the inclined plane forms with the horizontal is equal to `theta` the masses of the pulleys and threads as well as the frictions, are assumed to be negligible.

Find the acceleration of the block of mass m in the arrangement shown in the following figures. The masses of the pulleys and the threads, as well as the friction are assumed to be negligible.

The following parameters of the arrangement of figure are available: the angle alpha which the inclined plane forms with the horizontal, and the coefficient of friction k between the body m_1 and the inclined plane. The masses of the pulley and the threads, as well as the friction in the pulley, are negligible. Assuming both bodies to be motionless at the initial moment, find the mass ratio m_2//m_1 at which the body m_2 (a) starts coming down, (b) starts going up, (c) is at rest.
