What do you notice about the values of the Mass?__________________ Wat would you conclude the mass of the Sun to be?___________________ Now apply this equation to the galaxy F5631. Determine the mass M using the equation and the velocity at various distances rom the center of the galaxy given in the table below. Each of these resulting mass values gives mass enclosed within that distance. [Note that 1 kiloparsec (kpc) = 3.1 x 10^{19} meters]
What do you notice about the values of the mass as the distance increases? _____________________________________________________________ _____________________________________________________________ What would you conclude the mass of the galaxy to be? _____________________________________________________________ How much more massive is this galaxy than our Sun? _____________________________________________________________
