Three blocks are in contact with one another on a frictionless, horizontal surface as shown in the figure below. A horizontal force F is applied to mq. Take m, = 2.00 kg, m2 = 8.90 kg, m3 4.80 kg, and F = 15.5 N. m2 (d) Find the magnitudes of the contact forces between the blocks. N N between block 1 and 2 between block 2 and 3 (e) You are working on a construction project. A coworker is nailing up plasterboard on one side of a light partition, and you are on the opposite side, providing "backing" by leaning against the wall with your back pushing on it. Every hammer blow makes your back sting. The supervisor helps you put a heavy block of wood between the wall and your back. Explain how this change works to make your job more comfortable.
