A robotic inspection pod moves vertically in a shaft with constant acceleration. Upwards is the positive direction.
The table shows the velocity of the pod at two times.
| time in s\text{s}s | velocity in m/s\text{m/s}m/s |
|---|---|
| 2.0 | -6.0 |
| 5.0 | -1.5 |
Calculate the acceleration of the pod.
The pod continues with the same constant acceleration until 7.0 s.
Explain how the motion of the pod changes between 5.0 s and 7.0 s.
