Question

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?

Answer 1

100 rad/s

Step-by-step explanation:

Angular speed = linear speed / radius

ω = v / r

ω = (5.0 m/s) / (0.050 m)

ω = 100 rad/s
