(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The sled dog in figure (attached) drags sleds A and B across the snow. The coefficient of friction between the sleds and the snow is 0.10.

If the tension in rope 1 is 150 N, what is the tension in rope 2?

2. Relevant equations

F_a on b = -F_b on a

3. The attempt at a solution

The force diagrams I did for sled A and sled B resulted in:

Sled A: Fnetx = T1 - (mu_k)(m_a)(g) = 52

Sled B: Fnetx = T2 -T1 - (mu_k)(m_b)(g) = T2 - 228.4

My solution for T2 = 280 is very close, but not the right solution. Should I be adding another force for sled B, based on the friction of sled A or another component of sled A?
