1) A 0.5 kg wooden block is placed on top of a 1.0 kg wooden block. The coefficient of static friction between the two blocks is 0.35. If a Force of 20.0N is applied to the lower box. The coefficient of kinetic friction for the lower box and the table is 0.10? a. Draw the FBD for each box b. If a Force of 20.0N is applied to the lower box. Will the upper box slip with respect to the lower box? Explain. c. If the box is travelling at constant velocity what is the applied force acting on the lower box? What is the static friction on the lower box? (7) 0.5 kg 1.0 kg table
