In the arrangement shown, the springs are light and have stiffness k1 = 100 N/m and k2 = 200 N/m and the pulleys are ideal. An 8.0 kg block is suspended from the lower pulley is initially held at rest maintaining the strings straight and springs relaxed. Now the force supporting the block is gradually reduced to zero. How far does the block descend during the process of reduction of the force? Acceleration due to gravity is 10 m/s2,
