Concept Questions :-

(3) From given at graph it is clear that acceleration is increasing at constant rate

dadt=k (constant) ⇒ a=kt (by integration)

dvdt=ktdv=ktdt

dv=ktdtv=kt22

i.e. v is dependent on time parabolically and parabola is symmetric about v-axis.

and suddenly acceleration becomes zero. i.e. velocity becomes constant.

Hence (3) is most probable graph.
