Four airline baggage carts are coupled as shown in the figure to make a "train"; each has a mass of #250kg#. How do you find the answers to the following questions?
a. Find the force F that must be applied to accelerate this "train" at #0.8m/s^2# .
b. Find the tension in each of the three couplings between the baggage carts.

Explanation:
Given
#m> "Mass of each bag"=250kg," No . of bag"=4# #a> "acceleration of the train system"=0.8m/s^2#
Let Tension on three couplings are

#"Between bag A and B"=T_(AB)# 
#"Between bag B and C"=T_(BC)# 
#"Between bag C and D"=T_(CD)#
(a) Now the force to be applied on the system for creating
acceleration
(b)
#T_(AB)3xxmxxa=0#
#T_(BC)2xxmxxa=0#
#T_(CD)1xxmxxa=0#
