The earth spins on its axis once a day and orbits the sun once a year (365 1/2 days). Determine the average angular velocity (in rad/s) of the earth as it (a)spins on its axis and (b) orbits the sun. In each case, take the positive direction for the angular displacement to be the direction of the earth's motion. I thank you in advance for your time and help with this question. J.L.

Answer 1

First convert days to seconds.
1day*24hrs/1day*60mins/1hr*60sec/1min =86400secs.
Then you use the formula W=2TT/T
W= 2(3.14)/86400sec

Answer 2

First convert days to seconds.
1day*24hrs/1day*60mins/1hr*60sec/1min =86400secs.
Then you use the formula W=2TT/T
W= 2(3.14)/86400secs
Use the same conversion and formula for the second question.
