    I am struggling with this easy question and I really do not know why.
    Can someone help me?

    Find the acceleration:

    Objects A and B lie on a smooth horizontal surface and are connected by a light inextensible string.
    A has mass 8.2kg B has mass 2.3 kg. A is pulled with a force of 9 N, as shown. Find the acceleration of the system and the tension in the string.
    ------------------------------------------------------------------------------------------------------------------
    What I did:
    F=ma
    (1) 9-T=8.2a
    (2) T=2.3a
    (1)+(2)= 9=10.5a
    A = 0.86 ms^-2
    B = 1.97N

    I get the same. Why do you think they are incorrect?
