Question

How long does it take the baton to complete one spin?

A twirler’s baton is 0.76 m long and spins around its center. The end of the baton has a centripetal acceleration of 47.8 m/s2.

a.0.31 s

b.0.56 s

c.4.3 s

d.70 s

Answer 1

B

Step-by-step explanation:

Answer 2

The centripetal acceleration is given by:
a = 4π²R/T²

Using this formula,
47.82T² = 4π² x (0.76/2)
T = 0.56 s

The answer is B.
