2. The James Webb Space Telescope (JWST) is observed simultaneously from diametrically opposite ends of the Earth. (i) The parallax angle between these two observations is found to be w=1,750 arcsec. Compute the distance to JWST. [1] (ii) The mean proper motion of JWST is measured to be u = 100 deg year-1. What is the drift velocity of JWST (in ms-l) in its orbit relative to Earth? [2]
