Problem 1:
Copy the table shown below onto your HW and compare the magnitudes of the forces listed in the rst column to the magnitudes of each of the forces along the top row using symbols of =;>;<.The subscript H is for Hand. For example, comparing the FH;Ato FB;A results in FH;A>FB;A as FH;A must accelerate the system in front of it of 4 m at a, where FA;B must accelerate the system in front of it of 3 m at a. This in conjunction with the magnitude of FA;B being equal to FB;A (third law pairs), allows for the comparison to be made. Or it has to be larger so that the net force is to the right on block.

For example, comparing the FH, A to FB, A results in FHA FBA as FH,A must accelerate the system in front of it of 4 m at a where FA,B must accelerate the system in front of it of 3 m at a. This in conjunction with the magnitude of FA,B being equal to FB, A (third law pairs), allows for the comparison to be made. Or it has to be larger so that the net force is to the right on block A.

Q1.
for block A,
Fha-Fab=m*a...(1)
for block B
Fba-Fbc=2*m*a...(2)
for block c,
Fbc=m*a
then from equation 2, Fba=2*m*a+m*a=3*m*a
from equation 1,
Fha=4*m*a
for block D:
Fhd-Fde=2*m*a...(3)
fro block E:
Fde=m*a
then from equation 3, Fhd=3*m*a
so the table will look as below:
Fah Fba Fcb Fdh Fed
Fha = > > > >
Fab < = > = >
Fbc < < = < =
Fhd < = > = >
Fde < < = < =
