An elastic cord of constant K and length L is hung from point A having a massless lock at the other end. A smooth ring of mass M falls from point A , the maximum elongation of cord is

AB is a vertically suspended elastic cord of negligible mass and length L. Its force constant is k=(4mg)/L . There is a massless platform attached to the lower end of the cord. A monkey of mass m starts from top end A and slides down the cord with a uniform acceleration of g/2 . Just before landing on the platform, the monkey loses grip on the cord. After landing on the platform the monkey stays on it. Calculate the maximum extension in the elastic cord.

A smooth rubber cord of length l whose coefficient of elasticity is k is suspended by one end from the point O (figure). The other end is fittetd with a catch B. A small sleeve A of mass m starts falling from the point O. Neglecting the masses of the thread and the catch, find the maximum elongation of the cord.

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:

A metal wire of length L is suspended vertically from a rigid support. When a bob of mass M is attached to the lower end of wire, the elongation of the wire is l:

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

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 with the spring initially unstretched. Then the maximum extension in the spring is
