James holds one end of a rope tied at the top of the tower. James uses his hand to declares one end of a rope to rapidly descend, stopping at the other wrist. Pulse beginning to spread through the set-shaped graph sin which has an amplitude of -1 to 1. It is known that high james 60 cm, height tower is 5m, and the distance between james and tower is 1.5 m. questions: 1. Give a mathematical model of the movement of the rope by the initial pulse 2. Specify the time when the maximum amplitude of the impulses reach the top of the tower
