Question

The radius of the earth's very nearly circular orbit aroundthe sun is 1.50 x1011 m. Part A Find the magnitude of the earth's velocity asit travels around the sun. Assume a year of 365 days. Express your answer using twosignificant figures.   i got v =30  km/s for this one and its right..but ineed help with the other 2!
PartB - Find the magnitude of the earth's angularvelocity as it travels around the sun. Assume a year of 365days. Express your answer using twosignificant figures.

Explanation / Answer

Part B: since you get v=30m/s , we have: angular velocity = v/r = 30m/s / 1.50*1011 m= 2.0*10-10 rad/s part C: acceleration = v2 / r = (30m/s)2/ 1.50*1011 m = 6.0*10-9m/s2
