Question

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.​

Answer 1

Answer:

Option no D

Explanation:

Slope of distance-time graph gives the instantaneous velocity of the body. From the graph, the slope of graph is constant initially but after some time, slope continues to decrease and finally becomes zero. Thus we say that the particle starts with another constant velocity, then it changes its velocity and so the motion is in acceleration for some time and finally, the particle moves with another constant velocity.
