  1. Home End Swing Problem A swing moves a distance of 2m from one side to the other One complete swing movement takes πseconds. The swing starts at point ‘A’ A The equation for the distance d = Cos(4t) where t = time in seconds & d = horizontal distance from the centre point B B A When is the first time the swing is 0.6m from point ‘A’?

  2. Home End Swing Problem A swing moves a distance of 2m from one side to the other One complete swing movement takes πseconds. The swing starts at point ‘A’ A 0.6m The equation for the distance d = Cos(4t) where t = time in seconds & d = horizontal distance from the centre point d = 0.4 B B A Solve 0.4 = Cos(4t) 4t = Cos-1 0.4 When is the first time the swing is 0.6m from point ‘A’? 4t = 1.159 t = 1.159 ÷ 4 = 0.29sec (2dp)
