A 30000000kg object travels 500m in 30secs.Radius from the center of the path is 30m.What's the angular speed?

I'm sorry I don't remember the exact wording of the question but this is all the information given. I would really appreciate any help :)A 30000000kg object travels 500m in 30secs.Radius from the center of the path is 30m.What's the angular speed?
Angular speed, w = 胃/t, where 胃 = angular displacement, and


t = time





r = radius = 30m


s = 500m


t = 30 sec





Therefore, s = 胃r


胃 = s/r = 500m/30m = 16.67 rad


Hence, w = 16.67rad/30sec = 0.56 rad/sec





ANSWER: w = 0.56 rad/sec, angular speed





Hope this helps.
