The graph shows how the velocity v of an object moving in a straight line varies with time t from t = 0 to t = T. [Figure 8.1] Which graph represents the displacement s of the object in the time t = 0 to t = T?
This question uses a diagram from the original paper, which isn't shown here. Open the full paper from the past papers archive to see it.
Agraph showing displacement starting at zero, increasing to a positive maximum, then decreasing through zero to a negative minimum, and finally increasing back to zero displacement at t=T.
Bgraph showing displacement starting at zero, decreasing to a negative minimum, then increasing through zero to a positive maximum, and finally decreasing back to zero displacement at t=T.
Cgraph showing displacement always positive, increasing to a maximum, then decreasing, then increasing again to a lower maximum at T.
Dgraph showing displacement always positive, increasing, then decreasing, then increasing again to a similar maximum at T.
✓ Correct answer
A: graph showing displacement starting at zero, increasing to a positive maximum, then decreasing through zero to a negative minimum, and finally increasing back to zero displacement at t=T.
