a=F/m=αt/m……(i)
or a ∝ t
i.e. a-t graph is a straight line passing through
origin.
If u=0, then integration of Eq. (i) gives,
v=αt2/2m or v∝t2
Hence in this situation (when u=0) v-t graph is a
parabola passing through origin.
or a ∝ t
i.e. a-t graph is a straight line passing through
origin.
If u=0, then integration of Eq. (i) gives,
v=αt2/2m or v∝t2
Hence in this situation (when u=0) v-t graph is a
parabola passing through origin.

F=a.t
A) so acceleration a`=at/m
so it varies linearly
B) a`=dv/dt
therefore dv/dt=at/m
integrate it u get v=at^2/2m(constant of integration is 0 bcz initially particle at rest )
so it varies according to quadratic equation
C) as a`=at/m so t=ma`/a
hence v=m(a`)^2/2a
so it varies according to quadratic equation.
So A B C is the answer.
