For this exercise, assume that the earth is a sphere with a radius of 3960 miles and a rotation rate of 1 revolution per 24 hours.

A. Find the angular speed. Express your answer in units of rad/sec, and round to two significant digits.

Note: Let w = omega

After much struggles, I found w to be
0.000073 rad/sec.

B. Find the linear speed of a point on the equator. Express the answer in units of miles per hour, and round to the nearest 10 mph.

Can you set up B for me?
