SOLUTION: 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.

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.

.

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.

Solved.
