Problem

A satellite in an elliptical orbit receives a brief forward thrust exactly at apogee, increasing its speed at that point by 5%5\% without changing its position or mass. Which outcome is most likely for the new orbit? (a) The apogee distance increases while the perigee remains unchanged because the added kinetic energy pushes the satellite farther out at the burn point (b) The perigee distance increases because both angular momentum and mechanical energy have increased (c) The perigee distance decreases because the added kinetic energy makes the orbit more elongated (d) The orbit becomes circular because the new speed now matches the speed required for a circular orbit at that radius
