Answer to Question #4806 in Mechanics | Relativity for Jackson
If the yo-yo’s string is 0.14 m long, what is the yo-yo’s tangential speed?
Answer in units of m/s
where R=0.14 m - the yo-yo’s string
omega - angular velocity of the yo-yo
centripetal acceleration Wc=omega^2 *R
Hence Vt=omega*R=42.25*0.14=5.91 m/s
