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

Options

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 through out
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

A

Explanation

Slope is initially decreasing and then remains constant. So, velocity is initially decreasing i.e. the body undergoes retardation and ultimately stops. The body must have obviously started with some velocity.
