![43. In Example 5.7, we pushed on two blocks on a table. Sup-
QC pose three blocks are in contact with one another on a
frictionless, horizontal surface as shown in Figure P5.43
A horizontal force F is applied to m,. Take m
m2 3.00 kg, m, = 4.00 kg, and F= 18.0 N. (a) Draw a sep-
arate free-body diagram for each block. (b) Determine the
acceleration of the blocks. (c) Find the resultant force on
each block. (d) Find the magnitudes of the contact forces
between the blocks. (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 push-
on it. Every hammer blow makes your back sting. The
