At time t = 0, an object moves from rest with constant acceleration in a straight line. At time t, the object is distance s from its rest position. A graph is drawn of s against t^2 as shown. [graph of s against t^2: straight line through origin] Which statement describes the acceleration of the object?

1. AIt is equal to half the value of the gradient of the graph.
2. BIt is equal to the value of the gradient of the graph.
3. CIt is equal to twice the value of the gradient of the graph.
4. DIt is equal to the reciprocal of the gradient of the graph.
