Once a week you babysit your neighbor's toddler after school, usually going to
a local playground. You notice that each swing on the swing set takes nearly
the same amount of time, about 2.7 seconds. Use the pendulum formula
below to find out how long the swing is. Round your answer to the tenths
place.

Answer:

l = 1.8 feet

Step-by-step explanation:

Given that,

The time period of the pendulum, T = 2.7 seconds

We need to find the length of the swing. The formula for the time period of a simple pendulum is given by :

[tex]T=2\pi \sqrt{\dfrac{l}{g}}[/tex]

Where

l is the length of the swing.

[tex]T^2=\dfrac{4\pi^2l}{g}\\\\l=\dfrac{T^2g}{4\pi^2}\\\\l=\dfrac{(2.7)^2\times 9.8}{4\times 3.14^2}\\\\l=1.8\ \text{feet}[/tex]

So, the length of the swing is 1.8 feet long.
