A weight is suspended from a spring and allowed to hang at its rest position. It is then pulled down 2 inches, released, and allowed to oscillate up and down. Its location (in inches) relative to its rest position is given by the function f(t)= 2sin(2.5t - pi/2), where t is the time in seconds. How much time will it take for the weight to move through one complete cycle of motion?
