A wheel has a diameter of 13.37 inches.The linear speed is 18.33 ft per second.What is the angular speed in revolution per second?

Problem 2
A wheel has a 15cm diameter that rotates 7 radians/sec.what is the linear speed in meter per seconds?

The relationship between angular speed and linear speed is
$v = r \omega$
where v is the linear speed, r is the radius of the motion, and $\omega$ is the angular speed.
