As some students calculated this week. the planet Neptune has a planetary radius R. mass M. and rotates on its axis with a constant angular velocity (a- R=2.476x107m M= 1.02x 103mg (on. = 1.084 x 104radxs ( a) Through what angle will the planet rotate after 501 seconds? b) If the planet experienced an angular acceleration a = 0.27 radfsl. calculate its angular velocity after 23.2 seconds. c) With this acceleration. how many revolutions will the planet make after 23.2 seconds? d) Calculate the tangential velocity of the edge of Neptune at 23.2 seconds
