1. The problem statement, all variables and given/known data A satellite in orbit above Earths equator is traveling at an orbital speed of 7.45 km/s. a) Determine the altitude of the satellite b) Determine the satellites period 2. Relevant equations v = sqrt(Gm/r) 3. The attempt at a solution 7.45 * 1000 = 7450 m/s I plugged in the values to that equation and got a radius of 7.1 * 10^6 m. Now, I'm not sure how to find the altitude, but shouldnt it be the value I found (7.1*10^6m) minus earths radius? This gives me the value of 700 km For b, I'm not sure how to find the period, I tried T = 2pir / V where r was the radius I found and got 5988 seconds. Is this correct?
