I don't see the graph — could you upload the image or describe it (two points or the slope)?

How to get the answer: acceleration = slope of the speed–time graph = Δv / Δt. For example:
- If the speed is constant (horizontal line) the acceleration is 0 m/s².
- If speed rises from 0 to 10 m/s in 10 s, a = (10−0)/10 = 1.0 m/s².
- If speed rises from 0 to 10 m/s in 100 s, a = 0.10 m/s².
- If speed rises from 0 to 100 m/s in 10 s, a = 10 m/s².

Send the graph or two clear (v,t) points and I’ll compute which choice is correct.
