Homework Help: Physics

Posted by jameson on Sunday, September 23, 2012 at 7:23pm.

Three blocks are located on a horizontal frictionless table. They are connected by a massless cord, as shown in the figure, and pulled to the right. The masses of the three blocks are m1 = 22 kg, m2 = 21 kg, and m3 = 33 kg. The pulling force is equal to T3 = 53 N. What is the tension T2? I tried doing the acceleration times mass (21)and I got 14.6, which is apparently wrong. What is the right answer?
