1.	A space-ship is launched into a circular orbit close to the earth's surface. What additional velocity should now be impartedto 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 escapping `= V_(e) - V_(0) = 11.2 - 8 = 3.2 km//s`
