Question

A car moves in a straight line. The speed time graph of its motion is shown in figure 2.25.Plz don't spam. I want full answers.Answer ASAP. ​

Answer 1

Graphical Representation of 

Question: The graph shows position as a function of time for an object moving along a straight line. During which time(s) is the object at rest?

0.5 seconds

From 1 to 2 seconds

2.5 seconds

 



I only

II only

III only

none

Solution: Option B. Slope of the curve under the position-time graph gives the instantaneous velocity of the object. The slope of the curve is zero only in the time interval 1 < t < 2 s. Thus the object is at rest (or velocity is zero) only from 1 to 2 s. Hence option B is correct.

hope this is usefull
