Answer:

There is no deacceleration.

Explanation:

Let's check relation between velocity and acceleration

[tex]\\ \rm\Rrightarrow a=\dfrac{dv}{dt}[/tex]

[tex]\\ \rm\Rrightarrow a\propto dv[/tex]

So as velocity graph is going up acceleration is going up

Those flat lines on graph shows constant acceleration .

Curve lines up shows instantaneous acceleration.

If the graph is going down then it can be deacceleration .

Note :-No F is present in graph

Answer:

Explanation:

The car decelerates steadily to a stop so the line showing the deceleration will be a straight line from point D.

D is at 60s so 10s from D will be 70s. The car stops so velocity will be zero.

Based on the above, the line should look something like in the attached picture.
