Mathematics
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 about the same amount of time, about 2.2 seconds. use the pendulum formula below to find out how long the swing is. round your answer to the tenths place.

Ответ:
The lenght of the swing is 1.20 meters
Step-by-step explanation:
Hi, we have to apply the pendulum formula:
t = 2π√(L/g)
Where:
t = time (seconds)
L= Length ( meters)
g= gravity = 9.8 m/s2
Replacing with the values given:
2.2 = 2π√(L/9.8)
Solving for L
2.2/2π =√(L/9.8)
0.35 =√(L/9.8)
0.35² = L/9,8
0.122 x 9.8 = L
The lenght of the swing is 1.20 meters
