Answer to Question #199170 in Mechanics | Relativity for Blessings Kaira

Question

It takes the pendulum 3 seconds to swing from A through B to C and back to B. Calculate the periodic time of the pendulum.

Answer 1

Let time taken to reach A to B = x

Time taken to reach B to C = x

Time taken to reach C to B again = x

Total time = 3 s

$x+x+x=3$

$x=1\space s$

Total time taken to reach point A again $=3+1=4\space s$

therefore time period = 4 s
