A young boy swings a yo-yo horizontally above his head so that the yo-yo has a centripetal acceleration of 289 m/s (squared).

If the yo-yo's string is .78 m long, what is the yo-yo's tangential speed? Answer in units of m/s.

[tex]a=\frac{v^2}{r}[/tex]

v is the tangential speed and r is the radius.
