Motion And Time

Question

Wired Faculty App

A simple pendulum takes 32 s to complete 20 oscillations. What is the time period of the pendulum?

Solution

Number of oscillations = 20

Total time taken to complete 20 oscillations = 32 s

$Time period = \frac{Total time taken}{Number of oscillations} = \frac{32}{20} = 1.6 s$
