The spring has a force constant 5000N/m. The pulley is light and smooth. The spring and string are light. The suspended block A is of mass 10kg. If the block is slightly displaced vertically down from its equilibrium position and released. Find the period of its vertical oscillation.

(ii) In the figure-5.27, the spring has a force constant 5000 N m⁻¹. The pulley is light and smooth. The spring and the string are light. The suspended block A is of mass 1 kg. If the block is slightly displaced vertically down from its equilibrium position and released, find the period of its vertical oscillations.
