34.The magnitude of acceleration of blocks of mass

The magnitudes of accelerations of blocks of mass 2 kg and 4 kg are respectively . ( Pulleys and threads are massless) ( g = 10 m//s^(2 )

A block of mass 10 kg is put gently on a belt-conveyor system of infinite length at t = 0, which is moving with constant speed 20 m//sec towards right at all time. A constant force of magnitude 15 N is applied on the block continuously during its motion. The magnitude of acceleration of the block of mass 10 kg at t = 6s is

In the situation shown in fig., all the strings are light and inextensible and pullies are light. There is no friction at any surface and all blocks are of cuboidal shape. A horizontal force of magnitude F si applied to right most free end of string in both cases shown in the figure. At the instant shown, the tension in all strings are non-zero. Let the magnitudes of acceleration of large blocks (of mass M) in fig. be a_(1) and a_(2) respectively. Then,

The magnitude of acceleration of centre of mass of the system is

Two blocks A and B of equal masses are attached to a string passing over a smooth pulley fixed to a wedge as shown in figure. Find the magnitude of acceleration of centre of mass of the two blocks when they are released from rest. Neglect friction.
