Kinematics mcq question image

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 : the motion is retarded and finally the particle stops

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