A system consists of two identical cubes, each of mass `3kg`, linked together by a compressed weightless spring of force constant `1000Nm^-1`. The cubes are also connected by a thread which is burnt at a certain moment. At what minimum value of initial compression `x_0` (in cm) of the spring will the lower cube bounce up after the thread is burnt together?

A system consists of two identical cubes, each of mass m, linked together by the compressed weightless spring of stiffness ϰ (figure). The cubes are also connected by a thread which is burned through at a certain moment. Find: (a) at what values of Deltal , the initial compression of the spring, the lower cube will bounce up after the thread has been burned through: (b) to what height h the centre of gravity of this system will rise if the initial compression of the spring Deltal=7mg//ϰ .

A system consists of two identical blocks, each of mass m, linked together by the compressed weightless spring of stiffness k, as shown in figure -3.57. The blocks are connected by a thread which is burned through at a certain moment. Find (a) At what values of initial compression, the inital compression of the spring, the lower block will bounce up after the thread has been burned through To what height will the centre of gravity of this system will rise if the initial compression of the spring is 7 mg//k

A block of mass m=0.14kg is moving with velocity v_0 towards a mass less unstretched spring of force constant K=10Nm^-1 . Coefficient of friction between the block and the ground is mu=1//2 . Find the maximum value of compression in the spring (in cm), so that after pressing the spring the block does not return back but stops there permanently.

Two blocks of masses m and 2m compress a spring of spring constant k by x_(0) and blocks are a connected by a thread and placed on a smooth surface as shown. Now , thread is burned. Find the speed of each block when the spring attains its normal length L .

Two identical blocks each of mass 1kg are joined together with a compressed spring. When the system is released the two blocks appear to be moving with unequal speeds in the opposite directions as shown in fig. Choose the correct statement -
