A drone travels along a straight horizontal test track. The velocity-time graph below shows its motion over a period of 40 s as it starts from rest, accelerates uniformly at 2 m s-2 to a maximum velocity of v m s−1v\text{ m s}^{-1}v m s−1, and then maintains this velocity.
Given that the total distance travelled by the drone is 1200 m, find the value of vvv.
30 m s−130\text{ m s}^{-1}30 m s−1
40 m s−140\text{ m s}^{-1}40 m s−1
60 m s−160\text{ m s}^{-1}60 m s−1
120 m s−1120\text{ m s}^{-1}120 m s−1
