A body is projected vertically upward from the surface of earth is at same height at `t=5s` and `t=11s`. The speed with which it was projected is `Nm/s`. Find the value of `N`?

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

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 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.

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 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 with speed sqrt(g R_(e )) from the surface of earth. What is the maximum height attained by the body ? [ R_(e ) is the radius of earth, g is acceleration due to gravity]
