) A mass of 6 kg is resting on a horizontal with friction with a coefficient of static friction of 0.71 and coefficient of kinetic friction of 0.30. A force of 9 N is applied vertically upwards to the mass, and a force of 15 N is applied vertically downwards to the mass. What is the maximum static frictional force for this situation in Newtons?
