the earth's rate of rotation is constantly decreasing, causeing the day to increase in duration. in the year 2006 the earth takes about 0.840s longer to complete 365 revolutions than it did in the year 1906. what is the average angular acceleration of the earth? give your answer in rad/s^2
if anyone could help that would be sooooo great. its due tomorrow :(

we have the change in angular velocity, 2006 speed - 1906 speed is
(365x2xpi)/(365x24x60x60 + .84) - (365x2xpi radians)/(365x24x60x60)
that change in radians/sec happens over 100 years
ang accel = change in vel / (100x365x24x60x60)
it's going to be tiny!

Find the angular velocity in 2006 and subtract the angular velocity in 1906 then divide by the number of seconds in between. Tedious it may be but you may as well not bother with the course if you don't do the math. sorry but :"Whatever does not kill you makes you stronger! "(Conan)
