A 10. kg blоck оn а rоugh horizontаl surfаce is attached to a light spring (spring constant k=1.6×103 N/m). The block is pulled 8.0 cm to the right from its equilibrium position and released from rest. The frictional force between the block and surface has a magnitude of 30. N. What is the kinetic energy of the block as it passes through its equilibrium position?
