An unmanned rescue capsule moves along a straight test track. During one stage of the test, its acceleration is uniform.
| Time after the start of the test in s\mathrm{s}s | Velocity in m/s\mathrm{m/s}m/s |
|---|---|
| 4.0 | 9.0 |
| 7.0 | 18 |
The capsule maintains this acceleration until its velocity reaches 30 m/s.
Calculate the displacement of the capsule from 7.0 s until its velocity reaches 30 m/s.
