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 threads as well as the friction, are negligible. The ball is set on the same level as the lower end of the rod and then released. How soon will the ball be opposite the upper and of the rod?

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?

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?

if a mass of ball is m/2 and that of a rod is m the length of the rod is 20 cm the ball is set on the same level as the lower end of the rod and then released. If pulleys and strings are light, friction negligible how soon will the ball be opposite top the upper end 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.

In the arrangement shown in fig., mass of the rod M exceeds the mass m of the ball. The ball has an opening permitting it to slide along the thread with some friction. The mass of the pulley and the friction in its axle are negligible. At the initial moment, the ball was located opposite the lower end of the rod. When set free, both bodies began moving with constant accelerations. Find the friction force between the ball and the thread if t seconds after the beginning of motion, the ball got opposite to the upper end of the rod. The rod length equals l.

In the figure , mass of a ball is 9/5 times mass of the rod, Length of rod is 1m.The level of ball is same as rod level.Find out time taken by the ball to reach at upper end of rod.

Find the acceleration of rod A and wedge B in the arrangement shown in fig if the ratio of the mass of wedge to that of the rod equals eta and the friction between the contact surfaces are negligible.

Find the accelerations of rod A and wedge B in the arrangement shown in figure if the ratio of the mass of the wedge to that of the rod equals eta , and the friction between all contact surfaces is negligible.

In the arrangement shown in figure-2.124 pulley A and B are massless and the thread is inextensible. Mass of pulley C is equal to m. If friction in all the pulleys negligible, then :
