# Physics - pendulum negative work

A 2.20 kg pendulum starts from a height of 5.00m. It swings back and forth through one whole oscillation but only returns to a maximum height of 4.75m. After a long time the pendulum eventually winds down and comes to a stop. How much total negative work was done on the pendulum to bring it to rest at its lowest point?

I know that negative work during the first oscillation is 5.39 J.
