The block of mass m is released when the spring was in its natrual length. Spring constant is k. Find the maximum elongation of the spring.

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 ).

In the system as shown in figure, the blocks have masses m_(1) and m_(2) , the spring constant is k, coefficient of friction between the block of mass m_(1) and the surface is mu . The system is released with zero initial speed from the position where the spring is in its natural length.
