Question

Suppose a satellite weighs 720

pounds when sitting on the surface of the Earth, before it is

launched. Then it is placed in an Earth orbit

3.82×107 m from the center of the Earth. (This is 6.0

times the radius of the Earth). What is the force of gravity on the

satellite now? Give the answer in pounds. Do

"font-size:12pt;">convert pounds to Newtons, find the mass of the

satellite, or use

"font-size:12pt;font-family:CMMI12;">G

"font-size:12pt;">or

"font-size:12pt;font-family:CMMI12;">M⊕
