A graph labeled velocity versus time with horizontal axis time (seconds) and vertical axis velocity (meters per second). A blue line runs straight across at 2 units on the vertical axis for all horizontal axis values. Based on the graph of velocity over time, which could be the initial velocity and the final velocity for this graph? initial = 0 m/s; final = 2. 5 m/s initial = 2. 5 m/s; final = 2. 5 m/s initial = 3. 0 m/s; final = 6. 0 m/s initial = 6. 0m/s; final = 3. 0 m/s.
