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 in 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:
B
Average velocity `=(underset(0)overset(25)intvdt)/(25-0)=("Area of v-t graph between t=0 to t=25 s")/25=1/25[((25+10)/2)(20)]=14 m//s`
