Two bodies P of mass $2 \mathrm{kg}$  and Q of $1 \mathrm{kg}$ Are rigidly connected by a spring of force constant  $200 {\mathrm{Nm}}^{-1}$. From the rest position the body P is compressed by $2 \mathrm{cm}$ downwards. Determine the frequency of P and the energy of oscillation.

The period of oscillation of a mass $\mathrm{m}$  suspended by an ideal spring is $2 \mathrm{s}$. If an additional mass of $2 \mathrm{kg}$ be suspended, the time period is increased by $1 \mathrm{s}$ Find the value of $m$.

$10 \mathrm{kg}$ body is suspended from an ideal spring (force constant $250 {\mathrm{Nm}}^{-1}$. Calculate the time period of the body

A $10 \mathrm{kg}$ body is suspended from an ideal spring force constant $250 {\mathrm{Nm}}^{-1}$. If the body is displaced downwards by $30 \mathrm{cm}$ and released. With what speed it will pass through its mean position?

A $10 \mathrm{kg}$ body is suspended by an ideal spring (force constant $250 {\mathrm{Nm}}^{-1}$). What is the total energy in the body when it passes through mean position and body is displaced downward by $30 \mathrm{cm}$.

A $10 \mathrm{kg}$ body is suspended from an ideal spring (force constant $250 {\mathrm{Nm}}^{-1}$.) How much time it will take in reaching its mean position from its position of maximum displacement?

A $10 \mathrm{kg}$ body is suspended from an ideal spring (force constant $250 {\mathrm{Nm}}^{-1}$.  If the body is displaced by $40 \mathrm{cm}$ and released Calculate the time period of the body
