Question

The distance of a particle as a function of time is shown. 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.
• D. the particle starts with a initial velocity with constant acceleration and finally the particle moves with another constant velocity.

Answer 1

The correct option is A the particle starts with certain velocity, but the motion is retarded and finally the particle stops.

Slope gives velocity, which is changing.
If acceleration would have been constant distance would have increased.
