Question

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 periapsis (P) is given by M * Vp * Rp, where M is the mass of the satellite, Vp is the speed at periapsis, and Rp is the distance at periapsis. The angular momentum at apoapsis (A) is given by M * Va * Ra, where Va is the speed at apoapsis, Show more…

An artificial satellite is placed into an elliptical orbit around Earth. Telemetry data indicates that the periapsis of the orbit is 9.01 * 10^6 away from the center of the Earth and the apoapsis of the orbit is 28.2 * 10^6 away from the center of the Earth. The speed at the periapsis is Vp = 8945 m/s. Find the speed at the apoapsis.
