Question 1098168: The time T (in seconds) required for a pendulum to make one complete swing back and forth is approximated by T= 2π√L/10 where L is the length of the pendulum in metres. Calculate and round to the nearest thousandth the length of a pendulum that takes 2 seconds to make a complete swing. Use 3.14 for π. Answer by ikleyn(52781) (Show Source):
Substitute T = 2 seconds and pi = 3.14 into your basic equation.
You will get
2 = .
They want you solve it for L.
Square both sides. You will get
4 = (1)
Then L = .
You make all necessary calculations.
