An elevator is going up. The variation in the velocity of the elevator is as given in the graph. What is the height to which the elevator takes the passengers?

The variation of velocity of a particle with time moving along a straight line is illustrated in the following figure. The distance travelled by the particle in four seconds is

The time taken by a block of wood (initially at rest)to slide down a smooth inclined plane long (angle of inclination is ) is

A body is at rest at At it starts moving in the positive direction with a constant acceleration. At the same instant another body passes through moving in the positive direction with a constant speed. The position of the first body is given by after time and that of the second body by after the same time interval. Which of the following graphs correctly describes as a function of time

A frictionless wire is fixed on a sphere of radius . A very small spherical ball slips on this wire. The time taken by this ball to slip from to is

In figure, one car at rest and velocity of the light from head light is , then velocity of light from head light for the moving car at velocity , would be

A body starts from rest and moves with uniform acceleration. Which of the following graphs represent its motion

If the velocity of a particle moving along a straight line decreases linearly with its displacement from 20 to a value approaching zero m, then acceleration of the particle at m is

The graph of displacement time is Its corresponding velocity-time graph will be

The displacement-time graph of moving particle is shown below The instantaneous velocity of the particle is negative at the point

A body begins to walk eastward along a street in front of his house and the graph of his position from home is shown in the following figure. His average speed for the whole time interval is equal to

In a , H is the orthocentre and D is the mid point of Segment HD is produced to T such that HD=DT. Then the ratio equals to ;

Hence 2:1 is the correct option
