Tension on Three Blocks
Three blocks are located on a horizontal table. The coefficient of kinetic friction between the blocks and the table is 0.187. They are connected by a massless cord, as shown in the figure below, and pulled to the right. The masses of the three blocks are m1 = 8.0 , m2 = 8.0 , and m3 = 2.5 . The pulling force is equal to T3 = 91.0 .
What is the tension T2?
7.87×101 N

All you have to do is set up a ratio. Put the mass of all
three blocks together over the total number of N (for me it
was 10.5 kg/ 81 N) and set that equal to the sum of the
mass of the first and second blocks divided by "X" N.
Mine was 10.5 kg/81 N = 10 kg/ xN. So N was equal to about
77 N. Hopefully that makes sense. Good luck!
