A small block of mass m is fixed at upper end of a massive vertical spring of spring constant `k=(2mg)/(L)` and natural length `10L` The lower end of spring is free and is at a height L from fixed horizontal floor as shown. The spring is initially unstressed and the spring block system is released from rest in the shown position.
Q. As the block is coming down, the maximum speed attained by the block is

A ring of mass m is attached to a horizontal spring of spring constant k and natural length l_0 . The other end of the spring is fixed and the ring can slide on a horizontal rod as shown. Now the ring is shifted to position B and released Find the speed of the ring when the spring attains its natural length.

A block of mass m is attached with a spring in vertical plane as shown in the figure. If initially spring is in its natural length and the block is released from rest, then maximum extension in the spring will be

A ball of mass m is attached to the lower end of a light vertical spring of force constant K . The upper end of the spring is fixed. The ball is released from rest with the spring at its normal ( unstretched ) length, and comed to rest again after descending through a distance x .

An ideal spring with spring constant k is hung from the ceiling and a block of mass M is attached to its lower end. The mass is released when the spring is initially unstretched. Then the maximum extension in the spring is

A block of mass m is attached to one end of a mass less spring of spring constant k. the other end of spring is fixed to a wall the block can move on a horizontal rough surface. The coefficient of friction between the block and the surface is mu then the compession of the spring for which maximum extension of the spring becomes half of maximum compression is .
