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.

Options

A. Statement-I is true, Statement-II is true, Statement-II is correct explanation for Statement-I
B. Statement-I is true, Statement-II is true, Statement-II is NOT a correct explanation for Statement-I
C. Statement-I is true, Statement-II is false
D. Statement-I is false, Statement-II is true.

Answer

D

Explanation

If displacement is zero in given time interval then its average velocity also will be zero. E.g. particle projects vertically upwards.
