A) The particle starts with certain velocity but the motion is retarded and finally the particle stops
B) The velocity of the particle is constant throughout
C) The acceleration of the particle is constant throughout.
D) The particle starts with constant velocity, then motion is accelerated and finally the particle moves with another constant velocity
Correct Answer: A
Solution :
The slope of displacement-time graph goes on decreasing, it means the velocity is decreasing i.e. It's motion is retarded and finally slope becomes zero i.e. particle stops.
