In the arrangement shown in figure the mass of body 1 is `eta=4.0` times as great as that of body 2. The height `h=20cm`. The masses of the pulleys and the threads, as well as the friction, are negligible. At a certain moment body 2 is released and the arrangement set in motion. What is the maximum height that body 2 will go up to?

In the arrangement shown in figure the mass of the ball is eta times as that of the rod. The length of the rod is L the masses of the pulleys and the threats as well as the friction, are negligible. The ball is set on the same level as the lower and of the rod and then released. How soon will the ball be opposite the upper and of the rod?

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.
