A body projected from the surface of the earth attains a height equal to the radius of the earth. The velocity with which the body was projected is

A body attains a height equal to the radius of the earth. The velocity of the body with which it was projected is

The velocity with which a body should be projected from the surface of the earth such that it reaches a maximum height equal to 5 times radius R fo the earth is (M is mass of the earth )

A body attains a height equal to the radius of the earth when projected from earth's surface the velocity of body with which it was projected is

A body is projected vertically upwards from the earth's surface. The body reaches a height equal to one half of radius of earth. Calculate the initial speed with which the body was projected initially. Radius of earth = 6,400 km Mass of earth = 6 xx 10^(24) kg
