A parcel-sorting machine contains two compressed springs, R and S. Each spring is tested below its limit of proportionality.
| Spring | Applied force in N | Compression in mm |
|---|---|---|
| R | 18 | 12 |
| S | 14 | 28 |
Calculate the ratio of the spring constant of R to the spring constant of S.
