The slope of the velocity-time graph for motion with uniform velocity is equal to:

Match Column-$I$ with Column-$II$:

$A$ particle starts from rest and undergoes an acceleration as shown in the figure. The velocity-time graph from the figure will have which shape?

Explain instantaneous velocity and discuss how it can be determined from an $x-t$ graph.

The motion of an airplane is represented by a velocity-time graph as shown below. The distance covered by the airplane in the first $30.5 \ s$ is . . . . . . $km$.

The accompanying graph of position $x$ versus time $t$ represents the motion of a particle. If $p$ and $q$ are both positive constants,the expression that best describes the acceleration $a$ of the particle is
