The body makes 60 complete vibrations in one minute. What is the vibration frequency of this body?

From the condition of the problem, we know that the time during which the body completes a full cycle of oscillations is:

t = 1 min = 1 * 60 = 60 s

We also know that the number of complete vibrations made by the body for a given period of time is equal to:

N = 60

Thus, based on formula (1), we get:

υ = N / t = 60/60 = 1 s-1 = 1 Hz

That is, the vibration frequency of this body is 1 s-1 = 1 Hz.

Answer: 1 s-1 = 1 Hz
