Two springs A and B with spring constants $k_A$ and $k_B$ respectively ($k_A = 2k_B$) are stretched by the same force. If the energy stored in spring A is $E_A$, what is the energy stored in spring B?

A spring of natural length 'l' is fixed at one end and a block of mass 'm' is attached to its other end. The system rests on a smooth horizontal table. The block is pulled to extend the spring by an amount 'x' and then released. The total mechanical energy of the system at any instant during the oscillation, when the extension is 'y', is:

A block of mass 'm' is attached to two identical springs with spring constant 'k' each, connected in parallel. The block is displaced by 'x' from its equilibrium position and released. The maximum speed of the block during its subsequent oscillation is:

A spring with spring constant $k$ is compressed by a distance $x$. What is the potential energy stored in the spring?

If the spring constant of a spring is doubled, and the compression is halved, the potential energy stored in the spring will be:

A spring stores 4 J of potential energy when compressed by 0.1 m. What is its spring constant?

A spring of spring constant $k$ is compressed by a distance $x$. If the spring is cut into two equal halves and one half is compressed by the same distance $x$, what is the potential energy stored in the compressed half-spring?

Two identical springs, each with spring constant $k$, are connected in series. What is the effective spring constant of the combination?

A block of mass $m$ is attached to a spring with spring constant $k$. The block is pulled a distance $A$ from its equilibrium position and released. What is the maximum speed of the block during its oscillation?

A spring with spring constant $k$ is stretched by a distance $x$. The work done in stretching the spring is $W$. If the same spring is stretched by a distance $2x$, what is the work done?
