Figure shows the velocity time graph of ...

Figure shows the velocity time graph of a particle moving along straight line `(v` is m/s and `t` is in second). It average velocity in 20 seconds will be:
.

A

`10 m//s`

B

zero

C

`3.75 m//s`

D

`7.5 m//s`

Text Solution

Verified by Experts

The correct Answer is:
D
`V_(av)=("Displacement")/("time")`
Distance =area of curve
`V_(av)=((1)/(2)(10+20)(10))/(20)=(30)/(4)m//s`.
