The distance of a particle as a function of time is shown below. The graph indicates that
(A) The particle starts with certain velocity but the motion is retarded and finally the particle stops
(B) The velocity of the particle is constant throughout
(C) The acceleration of the particle is constant throughout in the direction of motion
(D) The particle starts with some constant velocity, the motion is accelerated, and finally
the particle moves with some constant velocity.
Help me to solve this question.
