Two initially stationary objects (mı = 5kg, m2 = 4kg) are connected as shown in the figure. There is only friction on the inclined plane and an external force of F = 40N applies to the object of mass m2. If the pulley is massless and frictionless, and the system is released; (Figure 1) Part A Find the frictional force acting on m2. Express your answer using three significant figures.

1. Two boxes are stacked on a frictionless table. M. = 4kg and M, 5kg. The coefficient of friction between the boxes is such that when a 27 N force F is applied to the lower box, the boxes start to slip relative to each other. The system is then restored to rest and force F is removed. A horizontal force F is now applied to the upper box. What is this force's maximum value in order for the two...
