A body is projected away from the earth's surface with a speed 3ve where ve is the escape velocity.The speed of the body at infinity will be:

A body is projected from the surface of the earth with thrice the escape velocity (V_(e)) from the surface of the earth. What will be its velocity, when it will escape the gravitational pull?

If a body is projected with a speed lesser than escape velocity, then

A body is projected vertically upward from the surface of the earth with escape velocity. Calculate the time in which it will be at a height (measured from the surface of the arth) 8 time the radius of the earth (R). Acceleration due to gravity on the surface of the earth is g.

Escape velocity for a projectile at earth's surface is V_(e) . A body is projected form earth's surface with velocity 2 V_(e) . The velocity of the when it is at infinite distance from the centre of the earth is :-

A body is projected vertically upward from the surface of the earth, then the velocity-time graph is:-

The escape velocity of a body from the earth is 11.2 km//s . If a body is projected with a velocity twice its escape velocity, then the velocity of the body at infinity is (in km//s )

A body is projected vertically upwards from the surface of the earth with a velocity equal to half of escape velocity of the earth. If R is radius of the earth, maximum height attained by the body from the surface of the earth is

A body is projected vertically upwards from the surface of earth with a velocity equal to half the escape velocity. If R be the radius of earth, maximum height attained by the body from the surface of earth is ( R)/(n) . Find the value of n.

A body is projected up from the surface of the earth with a velocity half the escape velocity at an angle of 30^(@) with the horizontal. Neglecting air resistance and earth’s otation, find (a) the maximum height above the earth’s surface to which the body will rise. (b) will the body move around the earth as a satellite?
