Answer:
3.9 units
Step-by-step explanation:
We are given that,
Time taken by each swing = 2.2 seconds
The pendulum formula is given by, , where T is the time taken and L is the length of the swing.
So, we have,
i.e.
i.e.
i.e.
i.e.
i.e.
i.e.
i.e. L = 3.923 units
So, rounded to tenths, the length of the swing is 3.9 units.
