At the high point of the graph velocity (slope of x - t curve) charges suddenly from a positive to a negative value. This is physically impossible.

Q. Statement I : $x - t$ graph, for a particle undergoing rectilinear motion, can be as shown in the figure.
Statement II : Infinitesimal changes in velocity are physically possible only in infinitesimal time.

If both Statement I and Statement II are true and the Statement II is correct explanation of the Statement I
