# YOUR Linear Speed?

**Students:**Use this applet to help you complete the

*How Fast Are You Spinning?*investigation given to you at the beginning of class. Some key questions to consider are listed below the applet.

## 1.

According to NASA's website, what is the Earth's mean equatorial radius?

## 2.

According to your answer for (1), what would Earth's circumference be?

## 3.

What would the linear speed of a person who lives on the Equator be? (Round your answer to the nearest 10 miles per hour).

## 4.

What is YOUR current latitude? (For Southern Hemisphere users, use a negative number. For Northern Hemisphere users, use a positive number.) .

## 5.

Use your answer for (3) and your result for (4) to determine YOUR LINEAR SPEED in miles/hr. (Round to the nearest 10 miles per hour). For a hint, interact with the applet above.
