Mech HW-42 Netoton's second and third lates 3. A hand pushes three identical bricks as shown. The bricks are moving to the left and speeding up. System A consists of two bricks stacked together. System B consists of a single brick. System C consists of all three bricks. There is friction between the bricks and the table. a. In the spaces provided at right, draw and label Free-body diagram for system A 1 A B 3 Free-body diagram for system B separate free-body diagrams for systems A and B. t 1 R Fr=HxN Na Mg M: Ma.(+2) Fr=H.M b. The vector representing the acceleration of system A is shown at right. Draw the acceleration vectors for systems B and C using the same scale. Explain. c. The vector representing the net force on system A is shown at right. Draw the net force vectors for systems B and C using the same scale. Explain. Acceleration of A Acceleration of B Acceleration of C Net force on A Net force on B Net force on C d. The vector representing the frictional force on system A is shown below. Draw the remaining force vectors using the same scale. JAT Explain how you knew to draw the force vectors as you did.
