ⓘ instructions
6 seconds
2 seconds
8 seconds

Explanation:

On a velocity-time graph, instantaneous acceleration equals the slope of the tangent line at that time. A steeper upward slope means larger positive acceleration; a steeper downward slope means larger negative acceleration.

1. At 2 seconds: The graph has an upward (positive) slope, so acceleration is positive.
2. At 6 seconds: The graph has a downward (negative) slope, steeper than at 8 seconds.
3. At 8 seconds: The graph has a downward (negative) slope, less steep than at 6 seconds.

Ranking from largest positive to largest negative: 2 seconds, 8 seconds, 6 seconds.

Answer:

1. 2 seconds
2. 8 seconds
3. 6 seconds
