YOUR Linear Speed?

Topic:
Circle, Sphere
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.
