The spring pendulum performed 16 oscillations in 4 s. Determine the frequency and period of its oscillations.

The oscillation period of a spring pendulum can be found by the well-known formula: T = t / n, where t is the oscillation time of the pendulum, n is the number of oscillations of this pendulum.
Let’s substitute all known values ​​into the formula and find the period of the pendulum’s oscillations: T = 4/16 = 0.25.
Answer: the period of oscillation of the spring pendulum is 0.25 s.
The oscillation frequency of a spring pendulum can be found by the well-known formula: v = 1 / T, where T is the period of oscillation of the pendulum.
Substitute the known values ​​into the formula and find the period of the pendulum’s oscillations: v = 1 / 0.25 = 4.
Answer: the oscillation frequency of the spring pendulum is 4Hz.
