A rocket is fired upwards. Its velocity versus time graph is shown in the figure-1.131. The maximum height reached by the rocket is:

A

7.1 km

B

79.2 km

C

72 km

D

infinite

Text Solution

Verified by Experts

The correct Answer is:
B
The maximum height reached by the particle is at `t = 12` sec. Hence, the area from `t = 0` to `t = 12` will give the maximum height.
