Question

The escape velocity from earth is 11.2 km per sec. If a body is to be projected in a direction making an angle 45° to the vertical, then the escape velocity is

Answer 1

the escape velocity is irrespective of the angle it is projected. So the escape velocity is 11.2 itself

Answer 2

Escape velocity is independent of angle of projection

therefor...escape velocity remain same i.e. 11.2 km/s
