Study the rotation curve for the spiral galaxy UGC 2885, which is shown in (Figure 1).

Use the orbital velocity formula to determine the mass of UGC 2885 enclosed within a radius of 30,000 light-years from its center. Suppose that the velocity at 30,000 light-years is 250 km/skm/s. (Hint: 1 light-year = 9.461×1015m9.461×1015m and mass of the Sun MSun=2×1030kgMSun=2×1030kg.)
