Answer 1

Answer:

sorry but there is no graph

Answer 2

Explanation:

Slope of the displacement-time graph gives the instantaneous velocity of the particle.

Region OA : Slope is (+) and decreasing i.e v decreases in positive direction.

⟹ The particle is retarding i.e a is negative (-)

Region AB : Slope is zero i.e v=constant .

⟹ The particle is moving with zero acceleration i.e a=0

Region BC : Slope is (+) and increasing i.e v increases in positive direction.

⟹ The particle is accelerating i.e a is positive (+)

Region CD : Slope is positive but constant i.e v=constant .

⟹ The particle is moving with zero acceleration i.e a=0
