Question

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

(a) the velocity of the particle is constant throughout 

(b) the acceleration of the particle is constant throughout 

(c) the particle starts with a constant velocity and is accelerated 

(d) the motion is retarded and finally the particle stops

Answer 1

Correct option (c) the particle starts with a constant velocity and is accelerated

Explanation:

From displacement-time graph, it is clear that in equal intervals of time displacements are not equal infact, decreases and after 40s displacement constant i.e. the particle stops.
