The initial velocity u required to project a body upward from the surface of earth to reach a height of 10 R, where R is the radius of earth, may be described in terms of escape velocity is :

The escape velocity from the surface of the earth is (where R_(E) is the radius of the earth )

Calculate the velocity with which a body must be thrown vertically upward from the surface of the earth so that it may reach a height of 10R , where R is the radius of the earth and is equal to 6.4 xx 10^(6)m. (Given: Mass of the earth = 6 xx 10^(24) kg , gravitational constant G = 6.7 xx 10^(-11) N m^(2) kg^(-2) )

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

The escape velocity of a body from the surface of the earth is equal to

A particle is throws vertically upwards from the surface of earth and it reaches to a maximum height equal to the radius of earth. The radio of the velocity of projection to the escape velocity on the surface of earth is

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

A particle is projected vertically with speed V from the surface of the earth . Maximum height attained by the particle , in term of the radius of earth R,V and g is ( V lt escape velocity , g is the acceleration due to gravity on the surface of the earth )

Show that if a body be projected vertically upward from the surface of the earth so as to reach a height nR above the surface (i) the increase in its potential energy is ((n)/(n + 1)) mgR , (ii) the velocity with it must be projected is sqrt((2ngR)/(n + 1)) , where r is the radius of the earth and m the mass of body.

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 thrown from the surface of the earth with velocity u m/s. The maximum height in metre above the surface of the earth upto which it will reach is (where, R = radish of earth, g=acceleration due to gravity)
