A rocket is fired and ascends with constant vertical acceleration of `10 m//s^(2)` for 1 minute. Its fuel is exhausted and it continues as a free particle. The maximum altitude reached is `(g=10 m//s^(2))`

A

18 km

B

36 km

C

72 km

D

108 km

Text Solution

Verified by Experts

The correct Answer is:
B
`h=(1)/(2)at^(2),v=at` max.height`=H=(v^(2))/(2g)`
Total distance from the ground`=(H+h)`
`=(1)/(2)at^(2)(1+(a)/(g))`
