1.
What is the gravitational force (magnitude and direction) on
the satellite from Earth?
2.
If we define g(r) to be the force of gravity on a mass m at a
radial distance r from the center of the Earth, divided by the mass
m, then evaluate the ratio g(r)/g(RE)to see how g varies with
radial distance. If...

A satellite of mass m is in an elliptical orbit around the
Earth, which has mass Me and radius
Re. The orbit varies from closest approach of
distance a at point A to maximum distance of

point A, the speed of the satellite is
v0. Assume that the gravitational potential
energy Ug = 0 when masses are an infinite distance
apart. Express your answers in terms of some or...
