14. Three masses of 1 kg, 6 kg and 3 kg are connected to each other by threads and are placed on table as shown in figure. What is the acceleration with which the system is moving ? Take g = 10 m s–2:

If you are talking about the system then consider all the three masses within a one mass system
.i.e tension force being internal forces hence it will not have any use.
thus system acceleration becomes:

a = F/(1 + 6 + 3) = F / 10 m/s^2.
common accelrn. fr all masses.

First draw the free body diagram of all the three masses. Then applying the Newton's second law of motion we get three equations 3g-T2=3a, T1-10=a, T2-T1=6a. solving these equations will give you a=2m/s
