2020 F = ma Exam B — Question 7

Two satellites are initially in identical circular orbits around the Sun, with orbital speed v = 1 × 104 m/s. The first satellite fires its thrusters toward the Sun, and quickly obtains a radial velocity of ∆vr = 1 m/s. The second satellite instead fires its thrusters behind it, and quickly increases its tangential velocity by ∆vt . If the two satellites subsequently perform orbits with the same period, approximately what was ∆vt ? — Source: Question 7, 2020 F = ma Exam B, © 2020 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
