A string is wound tightly around a fixed pulley whose radius is 5.0 cm. As the string is pulled, the

pulley rotates without slipping. What is the angular speed of the pulley when the string has a

linear speed of 5.0 m/s?

    100 rad/s

    Explanation:

    Angular speed = linear speed / radius

    ω = v / r

    ω = (5.0 m/s) / (0.050 m)

    ω = 100 rad/s
