The graph shows how the velocity v of an object moving in a straight line varies over time t = 0 to t = T. [Figure 7.1] 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.
Adisplacement-time graph that starts at zero, increases to a positive maximum, decreases through zero to a negative minimum, and returns to zero at t=T.
Bdisplacement-time graph that starts at zero, increases to a positive maximum, decreases to a positive minimum, increases to a second positive maximum, and returns to zero at t=T.
Cdisplacement-time graph that starts at zero, increases to a positive maximum, decreases to zero, increases to a second positive maximum, and returns to zero at t=T.
Ddisplacement-time graph that starts at zero, shows several oscillations with positive and negative displacement, and returns to zero at t=T.
✓ Correct answer
A: displacement-time graph that starts at zero, increases to a positive maximum, decreases through zero to a negative minimum, and returns to zero at t=T.
