The velocity of an object changes with time t as shown. [velocity-time graph: velocity on vertical axis, t on horizontal axis, straight line with negative gradient starting from positive velocity at t=0, crossing the t-axis and continuing to negative velocity] Which graph best shows the variation with time t of the displacement s of the object?

1. A[graph: s against t, curve rising from origin to a maximum then falling back down, like an inverted parabola] s t 0 0
2. B[graph: s against t, straight line rising from origin then a less steep straight line continuing to rise] s t 0 0
3. C[graph: s against t, curve rising from origin with decreasing gradient, levelling off] s t 0 0
4. D[graph: s against t, straight line rising from origin to a peak then straight line falling back to zero] s t 0 0
