1.	A space - ship is launched into a circular orbit close to the earth.s surface. What additional velocity should now be imparted to the space - ship in the orbit to overcome the gravitational pull. [Radius of earth = 6400 km and g=9.8 m//s^2 ]
Answer» Solution :Additional velocity to be IMPARTED to the ORBITING SATELLITE for ESCAPING = `V_e-V_0`=11.2-8 =3.2 km/s
