Answer:
The shape of satellite which is in the shape of parabola, opening upwards is, [tex]x^2=12 y[/tex], having vertex (0,0).
Comparing with general equation of parabola
[tex]x^2=4 a y[/tex] , having vertex (0,0) and focus (0,a).
Comparing the two above equation of parabola
4 a y = 12 y
4 a = 12
a=3
So, focus of the satellite which is in the shape of parabola=(0,3)
