The velocity-time graph for two bodies $A$ and $B$ is shown. Then the acceleration of $A$ and $B$ are in the ratio:

The following figures show velocity $v$ versus time $t$ curves. But only some of these can be realized in a particle. These are:

$A$ lift is going up. The variation in the velocity of the lift is given in the graph. What is the height to which the lift takes the passengers? (in $m$)

Consider a car initially at rest, starts to move along a straight road first with acceleration $5 \ m \ s^{-2}$, then with uniform velocity and finally, decelerating at $5 \ m \ s^{-2}$, before coming to a stop. Total time taken from start to end is $t = 25 \ s$. If the average velocity during that time is $72 \ km \ hr^{-1}$, the car moved with uniform velocity for a time of: (in $s$)

From the velocity-time graph of a particle moving in a straight line,decide which of the following is an incorrect statement.

The acceleration-time graph for a particle is given. What will be the corresponding velocity-time graph?
