At time 0 s, a remotely operated vehicle is moving east at a velocity of 3.0 m s−13.0\ \mathrm{m\,s^{-1}}3.0 ms−1. The table shows the resultant force on the vehicle over the next 10.0 s.
| Time interval | Resultant force |
|---|---|
| 0 to 4.0 s | 0 N |
| 4.0 to 6.0 s | Non-zero, east |
| 6.0 to 10.0 s | 0 N |
Describe the motion of the vehicle during each time interval and explain your answer.
