A mass of 4 kg is placed on a horizontal surface with a coefficient of kinetic friction of 0.29. A force is applied vertically downward to it and another force of 88 Newtons is applied at 11 degrees below the horizontal. As it moves 9 meters in the +x direction it loses 194 Joules of kinetic energy. What is the amount of the force which is applied downward in Newtons?

* the answers is 316.17, but how do you get that
