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"=(int_(0)^(25)vdt)/(25-0)=("Area of" v-t "graph between" t=0 "to" t=25s)/(25)[((25+10)/(2))(20)]=14 m//s`
