Fig. 2 (NCT).9 show the ` x-t` plot of a particle in one dimensional motion. Three different equal intervals of time are shown. In which interval the average speed is greatest and in which it is the least ? Give th sign of average speed for each interval.
.

A

`v_1 gt v_2`

B

`v_2 gt v_1`

C

`v_1 = v_2`

D

data is insufficient

Text Solution

Verified by Experts

The correct Answer is:
A

The average speed in a small interval of time is equal to the slope of x-t graph during that interval.
As slope of interval 1 gt slope of interval 2
`therefore` `v_1 gt v_2`

The velocity-time plot is shown in figure. Find the average speed in time interval t = 0 to t = 40 s during the period.

Assertion: The average velocity of a particle is zero in a time interval. It is possible that the instantaneous acceleration is never zero in the interval. Reason: The magnitude of average velocity in an interval is equal to its average speed in that interval.

If the object is moving with uniform velocity in a given interval of time, then the average speed and instantaneous velocity are equal, why?
