Given:
A pendulum swings back and forth 20 times in 34 seconds.
To find:
Time period of the pendulum.
Calculation:
The pendulum performs Simple Harmonic Motion while moving back and forth. Hence its motion can be described as oscillatory.
Time period of any oscillatory body is defined as the time taken to complete 1 full oscillation.
Applying Unitary Method:
20 oscillations are completed in 34 seconds
Therefore , 1 oscillation is completed in 34/20 = 1.7 seconds.
Hence , time period of pendulum is 1.7 seconds.
