A lift moves vertically in a straight shaft. Upwards is taken as the positive direction.
The table shows the velocity of the lift at two times.
| Time | Velocity in m/s |
|---|---|
| 08:15 | +2.0 |
| 08:20 | -2.0 |
Explain whether the lift has the same speed and the same velocity at these two times.
