Astring 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

t2 equal the displacement of the particle over the same time period if t2> t/2? hint: consider a sine wave starting at t1=0, then consider a closing wave starting at t1=0, for your explanatio

nah.   i'm just sleepy.
