Average velocity of a particle moving in a straight line, with constant acceleration a and initial velocity `u` in first `t` seconds is.

If average velocity of particle moving on a straight line is zero in a time interval, then

If average velocity of particle moving on a straight line is zero in a time interval, then

Identify the correct graph represeriting the motion of a particle along a straight line With constant acceleration with zero initial velocity.

Identify the correct graph represeriting the motion of a particle along a straight line With constant acceleration with zero initial velocity.

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 body starts with an initial velocity of 10ms-1 and is moving along a straight line with constant acceleration. When the velocity of the particle is 50ms- the acceleration is reversed in direction. The speed of the particle when it again reaches the starting point is
