Question 5. 10 pts An astronomer measures the radial velocities of 20 stars in a nearby star cluster, with average radial velocity VR = (51±16)km/s and average proper motion μ = (14.5 +6.0)"/century, with parallax angle p = (0.145 ± 0.060)". Proper Motion: =(14.5+ 6.0)"/century Radial Motion: PR=(51+16)km/s Star Cluster d Barycenter Compute the distance to the cluster, d and the magnitude of its space velocity, v = √√²+v along with their uncertainties, da and a, respectively, where the tangential velocity, VT, is given by the following equation. I Vr[km/s] =4.74 ["/yr] P["]
