Assuming a circular orbit for the Sun about the center of the Milky Way Galaxy, calculate its orbital speed using the following information: The mass of the galaxy is equivalent to a single mass \(1.5 \times 10^{11}\) times that of the Sun (or \(3 \times 10^{41} \mathrm{~kg}\)), located 30,000 ly away.
