The displacement of a particle as a function of time is shown in . It indicates
.

A

ainvelocity, but the motion is retarded and finally the particle stops.

B

The velocity of the particle dereases.

C

The accleration of the particle is in opposits direction to the velocty.

D

The particle stares with a constant velocity, the motion is accelerated and finaly pparticle moves with another constant velocity.

Text Solution

Verified by Experts

The correct Answer is:
A, B, C
Initially at origin, slope is not zero, so the pariticle has some initialvelcoty but with time we see that slope is decreasing and finally the slope becomes zero. So the particle stops finally. As the magnitude of velocityis decreasing, velocity and acceleratioin will be in oppsite derections.
