A 140 kg coffin that weighs 1370 N is dragged along the church floor with a rope at an angle of 45 degrees. The coffin moves along at a constant velocity when the priest and his helpers exert a force of 630 N. What is the coefficient of kinetic friction between the coffin and the church floor? What is the coffin's acceleration if the priest and his helpers exert a force of 1100 N?
