The time, in seconds, it takes for one complete swing of a pendulum is represented by the equation below, where is the length of the pendulum in meters, and is the acceleration due to gravity (9.81 m/s2). what is the approximate length of the pendulum if it takes the pendulum 2.5 seconds to complete one full swing? (use = 3.14)
