Escape velocity of a rocket is 11.2 km/s...

Escape velocity of a rocket is 11.2 km/sec. It is released at an angle of `45^(@)` . Its escape velocity is

A

11.2 m/sec

B

`11.2 sqrt(2)` km/sec

C

11.2 km/sec

D

22.3 km/sec

Text Solution

Verified by Experts

The correct Answer is:
C
The escape velocity is independent of the angle of projection. So, the escape velocity of the rocket remains same.
