Two is the minimum number of vectors that will sum to zero.
There is no minimum.
Assuming you want non-zero vectors, two opposing vectors will give a resultant of zero.
As, in the velocity-time graph, curves passes through zero means 'when time is zero velocity is zero'. Velocity is time derivative of displacement. So displacement is maximum or minimum when time is zero in position-time graph.
Set the first derivative of the function equal to zero, and solve for the variable.
