For a pendulum that completes fifteen complete swings in 34.8 seconds, how much is the frequency?

To find the frequency of a pendulum, we need to know the number of swings it completes in a given time period. In this case, the pendulum completes fifteen complete swings in 34.8 seconds.

To calculate the frequency, we'll use the formula:

Frequency = Number of swings / Time period

Plugging in the values we know:

Frequency = 15 swings / 34.8 seconds

Dividing these two values, we get:

Frequency = 0.431

Therefore, the frequency of the pendulum is approximately 0.431 Hz.

f = 1 / cycle time = 1 / (34.8 / 15)
