A light inextensible string that gas over a smoth fixed polley as shown in the figure connect two blocks of mases it `0.36` kg and `0.72` kg Taking `g = 10 ms^(-2)` , find the work done by the string on the block of mass ` 0.36` kg doring the first second after the system is released from rest ,

A light inextensible string that gas over a smoth fixed polley as shown in the figure connect two blocks of mases it 0.36 kg and 0.72 kg Taking g = 10 ms^(-2) , find the work done by the string on the block of mass 0.36 kg doring the first second after the system is refosed from rest ,

The two blocks in an Atwood machine have masses 2.0 kg and 3.0 kg. Find the work done by gravity during the fourth second after the system is released from rest.

Two blocks are connected by a massless string that passes over a frictionless peg as shown in Fig. 3E.46. One end of the string is attached to a mass m_(1) = 3 kg i.e. a distance R = 1.20 m from the peg. The other end of the string is connected to a block of mass m_(2) = 6 kg resting on a table. From what angle theta , measured from the vertical, must the 3 kg block be released in order to just lift the 6 kg block off the table ?

If the elevator in shown figure is moving upwards with constant acceleration 1 ms^(-2) , tension in the string connected to block A of mass 6 kg would be ( take, g =10 ms^(-2) )

Two blocks A & B are connected by a light inextensible string passing over a fixed smooth pulley as shown in the figure. The coefficient of friction between the block A and the horizontal table is mu=0.2 . If the block A is just to slip, find the ratio of the masses of the blocks.

Two unequal masses of 1 kg and 2 kg are attached at the two ends of a light inextensible string passing over a smooth pulley as shown in figure. If the system is released from rest, find the work done by string on both the blocks in 1 s. (Take g = 10 ms^(-2) )

An arrangement of the masses and pulleys is shown in the figure. Strings connecting masses A and B with pulley are horizontal and all pulleys and strings are light. Friction coefficient between the surface and the block B is 0.2 and between block A and B is 0.7 . The system is released from rest. (use g=10m//s^(2))
