82. (a) Because it is moving in a circular orbit, F/m must equal the centripetal acceleration: 2 80 N . 50 kg v r = But v = 2 π r/T , where T = 21600 s, so we are led to 2 2 4 1.6m/s r T π = 2 which yields r = 1.9 × 10 7 m. (b) From the above calculation, we infer v 2 = (1.6 m/s 2 ) r which leads to
