A 2.5-kg block is held at rest against a spring (? = 1200 N/m), compressing it ? = 5.0 cm from its equilibrium position, then released. There is no friction except where indicated otherwise.A. Just to the right of point ?, the block traverses a rough section, (represented by the thick line between ? and ?), losing half of its kinetic energy to friction. What is the block’s speed at point ??B. The rough section described in part (c) is 20 cm long. What isthe coefficient of kinetic friction? The image depicts a mechanical system featuring potential energy concepts. A block is shown attached to a spring. The spring is compressed by a distance $ d $ as indicated by the horizontal double-headed arrow.To the right of the block, there are three important positions marked along a track:- **Point A:** Represents the initial position of the block after it is released from the compressed spring.- **Point B:** An intermediate position on the track.- **Point C:** The final position, located at a lower elevation than point A, denoted by the vertical distance $ h $.The track from point A to point C includes a dip, indicating a change in elevation. The dashed horizontal line extending from point A to point B suggests the initial height level. Overall, the diagram illustrates the transition of potential and kinetic energy as the block moves from higher to lower elevations.
