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 acceleration of the particle varies
• C. the acceleration of the particle is constant throughout
• D. the particle starts with another constant velocity the motion is in acceleration and finally the particle moves with another constant velocity

Answer 1

The correct option is B the acceleration of the particle varies

It's not clear that the particle stop after some time, and the acceleration cannot be constant throughout as the particle may not be moving on a straight line. Option D is also incorrect as the velocity is not constant, which leaves us with option B.
