Problem 3. Block A with mass 2 kg is placed on top of Block B with mass 5 kg. The coefficient of kinetic friction between B and the ground is 0.2. A horizontal force F is applied to B. (a) Draw a free-body diagram for each block. What force accelerates A? (b) If both blocks accelerate to the right at 3m/s, what is the magnitude of F? (c) Find the minimum coefficient of static friction between the blocks such that both blocks can accelerate at 3m/s2 without A slipping. 2.00 kg 5.00 kg F
