A velocity-time graph increases linearly from 0 m/s at t = 0 s to 5 m/s at t = 2 s. What is the acceleration?

Explanation:
Acceleration is the rate at which velocity changes, and on a velocity–time graph that rate is shown by the slope. Here velocity increases from 0 m/s to 5 m/s over 2 s, so the change in velocity Δv is 5 m/s and the change in time Δt is 2 s. The slope = Δv/Δt = 5/2 = 2.5 m/s^2. Since velocity is rising, the acceleration is positive. So the acceleration is 2.5 m/s^2.
