A spacecraft is launched in a circular orbit very close to earth. What additional velocity should be given to the spacecraft so that it might escape the earth's gravitational pull.

A spaceship launched in a circular orbit very close to the earth. What additional velocity should be given to the spaceship so that, it might escape the velocity of earth’s gravitational pull.

A space-ship is launched into a circular orbit close to the Earth,s surface. What additional speed should now be imparted to the spaceship so that it overcome the gravitational pull of the Earth. Take kinetic energy of the space-ship, K = total energy of space-ship = (GMm)/(2R) where m = mass of space-ship, M= mass of the earth and R = radius of the earth.
