In the pulley-block system shown in figure, strings are light. Pulleys are massless and smooth. System is released from rest. In `0.3` seconds.
.

A ring of mass m can slide on the vertical smooth rod. Ring is connected by block with string as shown in figure. Pulley is of mass-less and smooth the system is released from reast. Initial tension in string is

In the system shown in figure, all surfaces are smooth, pulley and strings are massless. Mass of both A and B are equal. The system is released from rest. (a) Find the veca_(A). veca_(B) immediately after the system is released. veca_(A) "and" veca_(B) are accelerations of block A and B respectively. (b) Find veca_(A) immediately after the system is released.

Find the natural frequency of the system shown in figure. The pulleys are smooth and massless.

In the fig. m_(2) gt m_(1) . Pulley and string and massless and Pulley is smooth. The system is released from rest. After 2 seconds of motion m_(2) was held with the hand.

In the arrangement shown in fig., all pulleys are smooth and massless. When the system is released from the rest, acceleration of block 2 and 3 relative to 1 are 1 ms^(-2) downwards and 5ms^(-2) downwards, respectively. Acceleration of block 3 relative to 4 is zero. Find the absoulte acceleration of block 3.
