Question

The answer is not correct. Here's the problem. Suppose one of the Global Positioning System satellites has aspeed of 4.46 km/s at perigee and a speed of 3.64 km/s at apogee.If the distance from the center of the Earth to the satellite atperiee is 2.00 * 10^4 km, what is the corresponding distance atapogee? The answer is not correct. Here's the problem.

Explanation / Answer

at perigee, v = 4.46 km/s, r = 2.00 * 10^4 km, at apogee, v' = 3.64 km/s, r' = ? abgular momentum conservation: mvr = mvr' r' = r*(v/v') = 2.45* 10^4 km
