Determine the magnitude and direction of the friction force acting on the 100 kg block shown in the figure if P = 100 N. The coefficient of static friction is 0.20, and the coefficient of kinetic
friction is 0.17. The forces are applied with the block initially at rest. What is the maximum static friction that the surface can support? Is the equilibrium condition that is assumed for solving
the problem correct? What is the value of kinematic frictional force?
