The graph shows how the acceleration of an object moving in a straight line varies with time. [Figure 4.1] The object starts from rest. Which graph shows the variation with time of the velocity of the object over the same time interval?
AGraph A showing velocity starting at zero, increasing with a positive gradient (initially concave up, then concave down) to a maximum, then decreasing symmetrically with a negative gradient (concave down, then concave up) back towards zero.
BGraph B showing velocity starting at zero, increasing with a decreasing positive gradient to a maximum, then decreasing with an increasing negative gradient back towards zero, resembling a bell curve.
CGraph C showing velocity starting at zero, increasing to a maximum, decreasing to a minimum (negative velocity), then increasing back to zero, resembling a sine wave.
DGraph D showing velocity starting at zero and continuously increasing with an increasing positive gradient, resembling an exponential growth curve.
