circular motion question
Astronomical observations show that during the period from 1870 to 1900 the length of the day increased by about 6 x 10^-3 sec.
a) Express this increase as a fraction of a day. (1 day = 8.64x10^4 sec)
b) To what fractional change in the earth's angular velocity does this correspond?
