Statement-I : A particle moves in a straight line with constant acceleration. The average velocity of this particle cannot be zero in any time interval.
Statement-II : For a particle moving in straight line with constant acceleration, the average velocity in a time interval is `(u+v)/(2)`, where u and v are initial and final velocity of the particle of the given time interval.

A

Statement-1 is True, Statement-2 is True, Statement-2 is a correct explanation for Statement-1.

B

Statement-1 is True, Statement-2 is True, Statement-2 is NOT a correct explanation for Statement-1.
