The follwing graph shows the variation of velocity of a rocker with time. Then the mximum height attained by the rocket is.
.

A

`1.1 km`

B

`5 km`

C

`55 km `

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
Maximum height will be attained at `110 s`. Because after `110 s`. Velocity becomes negative and rocket will start coming down.
Area from `0` to `110 s` is
`(1)/(2) xx110 xx1000 = 55, 00 m = 55 km`.
