Physics: Gravitational force

Postby Guest » Tue Nov 29, 2011 10:31 pm

The Gravitational force (in newtons) exerted by the Earth on the space shuttle depends on "r", the shuttles distance in km from the earths center, and is given by F=GmMer-2.


Me=m5.97 x 1024 mass of earth in kg

m= 1.05 x 105 mass of shuttle orbiter in kg

G= 6.67 x 10-11 gravitational constant

Re=6380 radius of earth in km

A=1000 km max altitude of orbiter

based on the info, find the domain and range of the function

thank you so much to anyone who helps me!

Domain of the function - every value.
The range: [0; GmMER^2]
where R=6380
