The graph shown the variation of velocity of a rocket with time. Then, the maximum 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 110s. Because after 110 s, velocity becomes negative and rocket will start coming down.
Area from 0 to 110s is `(1)/(2) xx 110 xx 1000 = 55,000 m = 55 km`
