Spring of spring constant 1200 Nm^(-1) is mounted on a smooth fricationless surface and attached to a block of mass 3 kg . Block is pulled 2 cm to the right and released. The angular frequency of oscillation is

One end of a spring of force constant k_1 is attached to the ceiling of an elevator. A block of mass 1.5kg is attached to the other end. Another spring of force constant k_2 is attached to the bottom of the mass and to the floor of the elevator as shown in figure. At equilibrium, the deformation in both the spring is equal and is 40cm . If the elevator moves with constant acceleration upward, the additional deformation in both the spring is 8cm . Find the elevator's accelerationn ( g=10ms^-2 ).
