Two springs with negligible masses and force constant of k_(1)= 200 Nm^(-1) and k_(2)=160Nm^(-1) are attached to the block of mass m = 10kg as shown in the figure. Initially the block is at rest at the equilibrium position the block is at rest at the equilibrium position nor compressed. At time t=0, sharp impulse of 50 N-s is given to the block.
