Question

4. An artificial satellite is placed into an elliptical orbit around Earth. Telemetry data indicates that the periapsis of the orbit is r_p = 9.01 x 10^6 m away from the center of the Earth, and the apoapsis of the orbit is r_a = 28.2 x 10^6 m away from the center of the Earth. If the speed at the periapsis is v_p = 8945 m/s, find the speed at the apoapsis.

Step 1

The angular momentum at the periapsis is equal to the angular momentum at the apoapsis. Therefore, we can write: \(m \times v_p \times r_p = m \times v_a \times r_a\) where: \(v_p = 8945 \, m/s\) (speed at periapsis) \(r_p = 9.01 \times 10^6 \, m\) (distance at Show more…
