(a).
.Find the time taken by the pendulum to take a complete swing.
(a).

Answer to Problem 13CYU
about 9.5 seconds
Explanation of Solution
Given:
The time T in seconds that it takes a pendulum to make a complete swing back and forth is given by the formula
In Tokyo , Japan , a huge pendulum in the Shinjuku building measures 73 feet 9.75 inches
Formula Used:
1 inch = 0.083333 inches
Calculation:
Given:
9.75 inches =0.812496
Substitute
L = 73.8125
g = 32
The pendulum takes about 9.5 seconds to complete the swing.
(b).
Find the length of the pendulum.
(b).

Answer to Problem 13CYU
The length of the pendulum is about 324 feet.
Explanation of Solution
Given:
A clockmaker wants to build a pendulum that takes 20 seconds to swing back and forth .
Calculation:
Given:
Substitute
T = 20 seconds
g = 32
So, the length of the pendulum is about 324 feet.
