1.	An object is thrown from Earth is such a way that it reaches a point at infinity with non-zero kinetic energy [K.E(r=infty)=(1)/(2)MV_(infty)^(0)], with what velocity should the object be thrown from Earth?
Answer» SOLUTION :`V_(E) = sqrt(2g(R_(E)+H)) = sqrt(2g(R_(E) + oo))` `:. H = oo` `V_(e) = sqrt(V_(oo) + 2ghR_(E))`.
