Problem

The radio source 3C345 discussed in Box 4.3 has a redshift of z=z= .595. The angular velocity of the outward moving cloud C2C 2 is approximately .47 mas/yr. Assuming (contrary to fact) that the cloud is moving transverse to the line of sight, what velocity would be seen by an observer on station at 3C345 assuming a flat (k=0)(k=0), matter dominated FRW model of the universe with h=.72h=.72?
