A speedboat moves in a straight line along a channel. The table gives information about its motion during one time interval.
| initial velocity | final velocity | time interval |
|---|---|---|
| 3.0 m/s | 9.0 m/s | 4.0 s |
Calculate the speedboat's acceleration during the time interval.
Give the unit.
