The pulley in an atwood's machine is given an upward acceleration a. Find the acceleration of each mass and the tension in the string that connects them.(adsbygoogle = window.adsbygoogle || []).push({});

so my problem here is deriving the equation for the acceleration of both masses considering that the system was applied with an upward force. what will the upward acceleration do to the system? well, if the system wasn't given any upward acceleration i know that:

[tex]\sum[/tex]Fy_{1}= T_{1}-m_{1}g=-m_{1}a

[tex]\sum[/tex]Fy_{2}= T_{2}-m_{2}g=m_{2}a

are the tensions equal?

my professor didn't give us any values for the masses which make this problem even tougher for me. please help me.
