Kinematics Question 363
Question: The displacement of a particle as a function of time . It indicates that
Options:
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 it’s accelerated
D) the motion is retarded and finally the particle stops
Show Answer
Answer:
Correct Answer: D
Solution:
From displacement-tune graph, it’s clear that in equal intervals of time displacements are not equal in fact, decreases and after 40s displacement constant i.e. the particle stops.
