Help with pendulum problem

Question

The period of a pendulum is the time required for it to make one complete swing back and forth. The formula of the period P of a pendulum is P = 2(pi) times the square root of l over 32, where l is the length of the pendulum in feet. If a pendulum in a clock tower is 8 feet long, find the period. Use 3.14 for pi. 

Answer 1

The formula for the period of a pendulum is:

 

Period = 2Π*(Length/gravity)^(1/2)

 

Period =2*3.14*(8/32)^(1/2)

 

Period = 3.14 seconds
