A body is to be projected vertically upwards from earth's surface to reach a height of 9R , where R is the radius of earth. What is the velocity required to do so? Given g=10ms^(-2) and radius of earth =6.4xx10^(6)m .

The initial velocity v_(i) required to project a body vertically upward from the surface of the earth to reach a height of 10R, where R is the radius of the earth, may be described in terms of escape velocity v_(e ) such that v_(i)= sqrt((x)/(y)) xx v_(e ) . The value of x will be __________ .

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

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

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