An ideal massless spring can be compressed $2.33\ \mathrm{cm}$ by a force of $268\ \mathrm{N}$. A block of mass $m=3.18\ \mathrm{kg}$ is released from rest at the top of a frictionless incline of angle $32.0^\circ$. The block comes to rest momentarily after it has compressed this spring by $5.48\ \mathrm{cm}$.
- How far has the block moved down the incline at this moment?
- What is the speed of the block just as it touches the spring?
I really don't know where to start.
