Solution

The correct option is B Both statement 1 and statement 2 are correct and statement 2 is not the correct explanation of statement 1.
If displacement is a linear function of time then velocity is constant i.e. motion will be of uniform nature. The slope of the graph will always be same at every point, so instantaneous velocity and average velocity will be equal.
If acceleration is $0$ , then change is velocity is $0$ which means velocity is constant throughout and the particle continues to move along the same direction.

Q. Statement - 1 : For a particle undergoing rectilinear motion with constant acceleration, the average velocity cannot be equal for two different time intervals.
Statement -2 : The average velocity of particle moving with constant acceleration in a time interval is

\to u

is the initial velocity and

\to v

is the final velocity.

Q. Statement -1 : Let

v

be the speed of particle at any time

t

of a moving particle may be minimum at time

t = t_{0}

v = 0

v

of a moving particle may also be minimum at time

t = t_{0}
