The fig. shows the `v-t` graph of a particle moving in straight line. Find the time when particle returns to the starting point.

A

`30` sec

B

`34.5` sec

C

`36.2` sec

D

`35.4` sec

Text Solution

Verified by Experts

The correct Answer is:
C
For returning, the starting point
Area of `(DeltaOAB)=` Area of `(DeltaBCD)`
`1/2xx20xx25=1/2xxtxx4trArr t=5sqrt(5)cong11.2`
`:.` Required time `=25+11.2=36.2`
