In figure shown if 2 kg block is moving at an acceleration `2 m//s^(2)`, find the elongationin spring and acceleration of 4 kg block at this instant. Take ` g= 10m//s^(2)`.

`[0.012 m, 2 m//s^(2)]`

Find the acceleration of the two blocks shown in figure-2.101.Take g=10m//s^(2) [2m//s^(2), 2m//s^(2)]

Block C shown in figure-1.79 is going down at acceleration 2 m//s^(2) . Find the acceleration of blocks A and B.

A block of mass 10 kg, moving with acceleration 2m//s^(2) on horizontal rough surface is shown in figure

In the system shown in the adjoining figure, the acceleration of the 1 kg mass is m//s^(2) . (take g = 10 m//s^(2) )

In the figure ( g = 10 m//s^(2) ) .Acceleration of 2kg block is :

Top view of a block on a table is shown (g = 10 m//s^(2)) Find out the acceleration of the block.

A 2 kg block A is attached to one end of a light string that passes over an an ideal pulley and a 1 kg sleeve B slides down the other part of the string with an acceleration of 5m//s^(2) with respect to the string. Find the acceleration of the block, acceleration of sleeve and tension in the steing. [g=10m//s^(2)]

A block of mass 2 kg rests on the floor of an elevator , which is moving down with an acceleration 'g' , then the apparent weight of the block is [ take g = 10 m//s^(2) ]

A 2 kg block is present against a rough wall by a force F = 20 N as shown in figure .Find acceleration of the block and force of friction acting on it . (Take g = 10 m//s^(2))

A block of mass 1 kg and density 0.8g//cm^(3) is held stationary with the help of a string as shown in figure. The tank is accelerating vertically upwards with an acceleration a =1.0m//s^(2) .
