PS; I haven't got the answers..soc heck'em pls :) :

Q.10: v1-v2/u2+u1=1

therefore u1+u2=v2-v1------> D

Q.11:

You must write down the equations for both objects:

1) box-----> T-6= 2a----> T=28+6
2) 2 KG---> 2g-T=2a----> T=2g-2a

now we got 2 Ts equations:

8a+6=2g-2a

10a= 2g-6

a= 1.4---->A

Hope you got that :D
