Well I know work is the change in Ug and the Gravitational Potential Energy of two particles separated by a distance r is -GMm/r
Would e. just be GM/a? This seems to easy but then so did b. and c.
And then for f if Work = Change Ug then would it be
GMm/rf - GMm/ri
GMm/a - 2GMm/(a+b) = Work?
for a.
Ug = mgy
g = Fg/m
Fg = GMm/r2
therefore g = GM/r2
therefore Ug = GMmy/r2
y = r therefore Ug = GMM/r but U can't be positive so it's -GMm/r
But how do you write the appropriate definite integral?
For e. and f. Could you please elaborate, I looked again and tried to look up...
Homework Statement
A satellite of mass m is in an elliptical orbit around the Earth, which has mass M and radius R. The orbit varies from closest approach of 'a' at point A to maximum distance of 'b' from the center of Earth at point B. At point a the speed of the satellite is vo. Assume Ug...
