At a metro station, a girl walks up a stationary escalator in $20 \,sec$. If she remains stationary on the escalator, then the escalator take her up in $30 \,sec$. The time taken by her to walk up on the moving escalator will be

The given graph shows the variation of velocity (v) with position (x) for a particle moving along a straight line. Which of the following graph shows the variation of acceleration (a) with position (x)?

A particle shows distance-time curve as shown in the figure. The maximum instantaneous velocity of the particle is around the point

A body falls freely for $10\,sec$. Its average velocity during this journey (take $g = 10 \, ms^{-2}$)

A car moves from $A$ to $B$ with a speed of $30 \,kmph$ and from $B$ to $A$ with a speed of $20\,kmph$. What is the average speed of the car ?

A body starts from rest and moves with constant acceleration for $t \,s$. It travels a distance $x_1$ in first half of time and $x_2$ in next half of time, then

A person throws balls into air vertically upward in regular intervals of time of one second. The next ball is thrown when the velocity of the ball thrown earlier becomes zero. The height to which the balls rise is (Assume $g\, =\, 10\,ms^{-2})$

A train is moving slowly on a straight track with a constant speed of $2\, ms^{-1}$ passenger in that train starts walking at a steady speed of $2\, ms^{-1}$ to the back of the train in the opposite direction of the motion of the train. So to an observer standing on the platform directly in front of that passenger, the velocity of the passenger appears to be

A motorboat covers a given distance in $6$ hours moving downstream on a river. It covers the same distance in $10$ hours moving upstream. The time it takes to cover the same distance in still water is..........

A body of mass $'m'$ moving along a straight line covers half the distance with a speed of $2\, ms^{-1}$. The remaining half of the distance is covered in two equal time intervals with a speed of $3\, ms^{-1}$ and $5\, ms^{-1}$ respectively. The average speed of the particle for the entire journey is

A body is projected vertically upwards. The times corresponding to height $h$ while ascending and while descending are $t_1$ and $t_2$ respectively. Then the velocity of projection is ($g$ is acceleration due to gravity).

From the top of a tower of two stones, whose masses are in the ratio $1 : 2$ are thrown one straight up with an initial speed $u$ and the second straight down with the same speed $u$. Then, neglecting air resistance
