CONTEXT-RICH, ENGINEERING APPLICATION Suppose the Sun could collapse into a neutron star of radius as in 89. Your research team is in charge of sending a probe from Earth to study the transformed Sun, and the probe needs to end up in a circular orbit from the neutron- Suns center. (a) Calculate the orbital speed of the probe. (b) Later on, plans call for construction of a permanent spaceport in that same orbit. To transport equipment and supplies, scientists on Earth need you to determine the escape speed for rockets launched from the spaceport (relative to the spaceport) in the direction of the spaceports orbital velocity at takeoff time. What is that speed, and how does it compare to the escape speed at the surface of Earth?
