A mass of 9 kg rests on a floor with a coefficient of static friction of 1.25 and coefficient of kinetic friction of kinetic friction of 0.1. One force is applied vertically downward of 10 Newtons and another force is applied at an angle of 15 degrees below the horizontal. Calculate what the magnitude this force needs to be in order to begin to move the mass. If the same amount of force is applied at the same angle above...
