Question
The angular speed of a point on Earth is $\frac{\pi}{12}$ radian per hour. The Equator lies on a circle of radius approximately 4000 miles. Find the linear velocity, in miles per hour, of $\overline{\mathbf{a}}$ point on the Equator.
Step 1
Step 1: The formula to find the linear velocity is given by $v = r \cdot \omega$, where $v$ is the linear velocity, $r$ is the radius, and $\omega$ is the angular speed. Show more…

The angular speed of a point on Earth is $\frac{\pi}{12}$ radian per hour. The Equator lies on a circle of radius approximately 4000 miles. Find the linear velocity, in miles per hour, of a point on the Equator.
The angular speed of a point on a planet is 7π/8 radian per hour. The equator lies on a circle of radius approximately 5000 miles. Find the linear velocity, in miles per hour, of a point on the equator. The linear speed of a point on the equator is approximately miles per hour. (Round to the nearest whole number as needed.)
