The velocity-time graph of a car moving ...

The velocity-time graph of a car moving along a straight road is shown in figure. The average velocity of the car is first `25` seconds is

A

`20 m//s `

B

`14 m//s`

C

`10 m//s`

D

`17.5 m//s`

Text Solution

Verified by Experts

The correct Answer is:
2
Average velocity = `(overset(25)underset(0) (int)vdt)/(25-0)= ("Area of v-t graph between t=0 to t=25 s")/(25) = (1)/(25) [((25+10)/(2))(20)]= 14 m//s`
