**Physics Problem: Block and Spring System**

**(a)** A 15.0 kg block is released from rest at point A in the figure below. The track is frictionless except for the portion between points B and C, which has a length of 6.00 m. The block travels down the track, hits a spring of force constant 2,200 N/m, and compresses the spring 0.250 m from its equilibrium position before coming to rest momentarily. Determine the coefficient of kinetic friction between the block and the rough surface between points B and C.

*[Input field for answer]*

**(b)** *What If?* The spring now expands, forcing the block back to the left. Does the block reach point B?

- [ ] Yes
- [x] No ✔️

If the block does reach point B, how far up the curved portion of the track does it reach, and if it does not, how far short of point B does the block come to a stop? (Enter your answer in m.)

*[Input field for answer in m]*

**Diagram Explanation:**

- The diagram shows a track with a curved section and a straight section.
- The block is initially placed at point A, which is 3.00 m high.
- Points B and C are part of the straight section, and the surface between them is rough and 6.00 m long.
- A spring is located at point C, represented by a coiled symbol.
- The block compresses the spring by 0.250 m before momentarily stopping.

This problem involves concepts such as gravitational potential energy, kinetic energy, and the work-energy principle in the context of a block-spring system with friction.
