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?
✓ Correct Answer
The correct answer is 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.
