The horizontal displacement of a swinging pendulum is given by :1? (t) = 1. 5 COS (t)_0'05t where x(t) is the horizontal displacement, in cm, from the lowest point of the swing as a function of time, t, in seconds. Determine the FIRST time the swing would change its direction of motion. State the final equation you solved to get this time. Solution format: 1.01 seconds, f(t) = 2/3
