1.	In the arrangement shwon, initially both springs are in their natural length l_(0). The left spring has force constnat k_(0)=2N//m and the force constant of the right spring varies as k=k_(0)x, wherex is its compression. The mass of the block is 10/3 kg. At time t=0, the block is given a right ward velocity v_(0)=2 m/s. Both the springs are massless. When the blcok comes to instantaneous rest th energy stored in the left spring is
