Question

A pendulum is set in motion and timed. The time measured for 20 complete swings is 30 s. What is the time for one complete swing of the pendulum?

Answer 1

Time = 1.5 seconds

Step-by-step explanation:

Given the following data;

Number of swings = 20

Total time = 30

To find the amount of time for each swing, we would use the following mathematical expression;

Time = total time/number of swings

Time = 30/20

Time = 1.5 seconds
