Figure shows a system consisting of a massless pulley, a spring of force constant k and ablock of mass m. If the block is slightly displaced vertically down from its equillibrium position and then released, find the period of its vertical oscillation in cases (a) & (b).

A block of mass m hangs from a vertical spring of spring constant k. If it is displaced from its equilibrium position, find the time period of oscillations.

A block of mass m is connected with two ideal pullies and a massless spring of spring constant K as shown in figure. The block is slightly displaced from its equilibrium position. If the time period of oscillation is mupisqrt(m/K) . Then find the value of mu .

A rectangular tank having base 15 cm xx 20 cm is filled with water (density rho = 1000 kg//m^(2)) up to 20 cm and force constant K = 280 N//m is fixed to the bottom of the tank so that the spring remains vertical. This sysytem is in an elevator moving downwards with acceleration a = 2 m//s^(2) . A cubical block of side l = 10 cm and mass m = 2 kg is gently placed over the spring and released gradually, as shown in the figure. a. Calculate compression of the spring in equilibrium position. b. If the block is slightly pushed down from equilibrium position and released, calculate frequency of its vertical oscillations.

In the system shown in the figure the string, springs and pulley are light. The force constant of the two springs are k_(1) = k " and " k_(2) = 2k .
