1. The problem statement, all variables and given/known data A 320kg satellite experiences a gravitational force 800N. What is the radius of the satellite's orbit? 2. Relevant equations G m1m2 / d^2 3. The attempt at a solution I started with 800N = (G(320kg)(5.98(10^24)kg) / d^2 After some algebra and rounding I ended up with d = 40,000 km. Is that reasonable?
