Home Swing Problem End A swing moves a distance of 2m from one side to the other One complete swing movement takes π seconds. The swing starts at point ‘A’ A The equation for the distance d = Cos(4t) where t = time in seconds B B A During the first 4 cycles how long is the swing at least 80cm from point ‘A’?

Home Swing Problem End A swing moves a distance of 2m from one side to the other One complete swing movement takes π seconds. The swing starts at point ‘A’ A 0.8m The equation for the distance d = Cos(4t) where t = time in seconds d = 0.2 B B A Find Total Time ‘T’ Solve 0.2 = Cos(4t) During the first 4 cycles how long is the swing at least 80cm from point ‘A’? time difference = 0.89 4t = Cos-1 0.2 4t = 1.37 or 4.91 T = 4 x 0.89 = 3.54 sec t = 0.34 or 1.23
