Solution

The correct option is B $B$
We know that
$A c c e l e r a t i o n (a) = \frac{d V}{d t}$
In the velocity time graph, slope at any point gives the acceleration at that point.
In this problem, slope is maximum at point $B$ . Hence, the rocket have the greatest acceleration at point $B$ .

The graph shows how the velocity 'V' of a firework rocket changes with time t. at which point on the graph does the rocket have the greatest acceleration?

The correct option is B BWe know thatAcceleration (a)=dVdtIn the velocity time graph, slope at any point gives the acceleration at that point.In this problem, slope is maximum at point B. Hence, the rocket have the greatest acceleration at point B.
