A very light spring of equilibrium length 10.0 cm is hung from the ceiling with a 0.40 kg block at its end. When the block settles, the spring is 15.0 cm long. The same block-and-spring system is then set up horizontally on the floor, with the free end of the spring attached to a wall. The block is pulled 16.0 cm from the wall and released from rest. It slides with negligible friction. Find the block's distance from the wall 0.35s after it was released from rest, at 16.0 cm from the wall.
