Atwirlers baton is 0.76 m long and spins around a its center. the end of the baton has a centripetal acceleration of 47.8 m/s2.
how long does it take the baton to complete a spin?
a. 0.31 s
b. 0.56 s
c. 4.3 s
d. 70 s

The correct answer for this question is this one: "B. 0.56 s"

A twirlers baton is 0.76 m long and spins around a its center. The end of the baton has a centripetal acceleration of 47.8 m/s2. It takes 0.56 s for the baton to complete a spin
Hope this helps answer your question and have a nice day ahead.

Answer;

B. 0.56 seconds

Explanation and solution;The centripetal acceleration is given by:

       a = 4π²R/T² , where R is the radius of the circular path and T is the time in seconds and a is the centripetal acceleration.

Therefore;  using this formula,

47.82T² = 4π² x (0.76/2)

T = 0.56 s
