| (a) | Quantity \(B\) may represent time. |
| (b) | Quantity \(A\) is velocity if motion is uniform. |
| (c) | Quantity \(A\) is displacement if motion is uniform. |
| (d) | Quantity \(A\) is velocity if motion is uniformly accelerated. |
| (a) | The particle was released from rest at \(t = 0\). |
| (b) | At \(B,\) the acceleration \(a > 0\). |
| (c) | At \(C,\) the velocity and the acceleration vanish. |
| (d) | Average velocity for the motion between \(A\) and \(D\) is positive. |
| (e) | The speed at \(D\) exceeds that at \(E\). |
