A body Is projected horizontally near the surface of the earth with `sqrt(1.5)` times the orbital velocity. Calculate the maximum height up to which it will rise above the surface of the earth.

A body is projected horizontally near the surface of the earth with sqrt(1.5) times the orbital velocity .Calculate the maximum heght up which it will rise above the surface of the earth. [Hint : when the velocity of projection exceeds the orbital velocity the path taken is an ellipse At the highest point the radius vector and velocity are right angles Conserve angular momentum and energy.]

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.

From the surface of earth, a body is projected upwards with a kinetic energy equal to one-third of the energy required to escape. Calculate the height up to which the body will rise above the surface of earth.

An object is thrown vertically upwards from the surface of the earth with a velocity x times the escape velocity on the earth (x lt 1) , then the maximum height ot which its rises from the centre of the earth is (radius of earth is R)

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

An object is projected vertically upward from the surface of the earth of mass M with a velocity such that the maximum height reached is eight times the radius R of the earth. Calculate: (i) the initial speed of projection (ii) the speed at half the maximum height.

A body is projected vertically up from surface of the earth with a velocity half of escape velocity. The ratio of its maximum height of ascent and radius of earth is
