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

3. The system shown below has an acceleration of magnitude 2.00 m/s. 4.00 kg 9.00 kg 140.0 40.0%% Assume the coefficients of kinetic friction between block and incline are the same for both inclines. a. Draw the FBD b. Find the coefficients of kinetic friction c. Find the Tension in the string d. What would the coefficient of static friction (minimum) would prevent this system moving in the first place? (7)
