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?
