$A$ ball is thrown vertically upwards. Which of the following graphs represents the velocity-time graph of the ball during its flight (air resistance is neglected)?

The position $x$ of a particle moving in one dimension under the influence of a constant force is given by $t = \sqrt{x} + 3$,where $x$ is in meters and $t$ is in seconds. Find the displacement of the particle in $m$ when its velocity becomes zero.

$A$ particle moves along the $x$-axis in such a way that its $x$-coordinate varies with time according to the equation $x = 4 - 2t + t^2$. The velocity of the particle will vary with time as:

The graph of displacement $s$ versus time $t$ is given below. Its corresponding velocity-time graph will be:

The graph shows the variation of velocity of a rocket with time. The maximum height attained by the rocket is ........... $km$ :-

How can instantaneous velocity be found by the graphical method?
