Determine the period and frequency of oscillations of a material point that has made 50 complete oscillations in 20 s.

We write down a short record of the condition.
n = 50 (total number of vibrations);
t = 20 s. (the time during which the given number of oscillations was made).
T -? (oscillation period).
υ -? (vibration frequency).
To calculate the oscillation period, we apply the following formula:
T = t / n;
The period is the ratio of time to the number of oscillations during this time.
Substitute the values and get:
T = 20/50 = 0.4 s.
Frequency opposite to the period:
υ = 1 / T;
Substitute the values and find:
u = 1 / 0.4 = 2.5 Hz.
