The Earth rotates once around itself every day, so in 24 hours. However, the circle YOU complete depends on where on the Earth you are. If you are at one of the poles, you don't move, just rotate. The largest circle is at the equator.
(a) What is your speed due to the Earth's rotation, if you are at the equator? What is your acceleration due to the Earth's rotation, if you are at the equator? You are actually in Milwaukee. This is at a latitude of 43.04 degrees North. What is your speed due to the Earth's rotation, if you are in Milwaukee? What is your acceleration due to the Earth's rotation, if you are in Milwaukee? (Hint: The circle you make is LESS than 2? Rearth, so you need to calculate the radius of the circle you follow. Confused? Well, imagine you were at the North Pole. The circle you make is ZERO meters!)
