Task data: n (number of revolutions of the carousel) = 15 revolutions; t (duration of rotation of the carousel) = 1 min (in SI t = 60 s).
1) The period of rotation of the considered carousel: T = t / n = 60/15 = 4 s.
2) Rotation frequency: ν = n / t = 15/60 = 0.25 Hz.
Answer: The rotation period of the considered carousel is 4 s; its rotation frequency is 0.25 Hz.
