Question

The displacement of a body as a function of time is shown in figure. The figure indicates that

• A. the body starts with a certain velocity, but the motion is retarded and finally the body stops.
• B. the velocity of the body is constant throughout
• C. the acceleration of the body is constant throughout
• D. the body starts with a constant velocity, the motion is accelerated and finally the body moves with another constant velocity.

Answer 1

Answer: (A)

the body starts with a certain velocity, but the motion is retarded and finally the body stops.

The slope of the Displacement-Time curve is Velocity.

In this case the slope is decreasing through out the motion that means this is decelerated motion, after some time slope becomes zero that means the motion stops.
