1. The problem statement, all variables and given/known data 2. Relevant equations Sum of Force g = 32.174 ft/ s^2 3. The attempt at a solution I consider the right hand side weight, T = -mg = - 10*32.174 = 321.74 lb Why is the answer 3.33, which seems to be even smaller than the mass?? Should I consider the momentum, or something with the 5 lb mass?? Thanks.
