A pendulum is constructed of a 6.7 gram mass suspended on a 55cm thread. The mass is displaced vertically 55 cm to a point exactly horizontal from the top of the thread and released. The mass swings down and is cut directly above the mass when the mass is 120 cm above the floor. The mass is released from the string and lands on the floor in front of the pendulum. How far did it travel from the position it was cut? O_O HEEEELLP!!!
