The figure shows the velocity (v) of a particle plotted against time (t).  <img  src="https://d10lpgp6xz60nq.cloudfront.net/physics_images/DCP_V01_CH6_E01_153_Q01.png"  width="80%">">">

a
The particle changes its direction of motion at some point
b
The acceleration of the particle remains constant
c
The displacement of the particle is zero
d
The initial and final speeds of the particle are the same

detailed solution

Correct option is A

For tT, v=+ve At t=T, v=0∴ Particle changes direction of velocity at t=Ts= Net area of v-t graph =0a= Slope of v-t graph = constant
