A 20 centimeter pendulum swings in front of a metric ruler. The bob(Weight on the end of the pendulum) is releases from a position of 36 centimeters. It swings to the 14 centimeter positionbefore winging back to 36 centimeters.
What is the period of the pendulum?=
2pi sqrt(20cm/(980(cm/s^2)))= 9 sec.
How did they get that answer? Could you show all the steps?
