Need help with homework problem

  1. Sep 12, 2007 #1
    1. The problem statement, all variables and given/known data
    In Figure 5-65, a force of magnitude 13 N is applied to a FedEx box of mass m2 = 1.2 kg. The force is directed up a plane tilted by ? = 38°. The box is connected by a cord to a UPS box of mass m1 = 5.0 kg on the floor. The floor, plane, and pulley are frictionless, and the masses of the pulley and cord are negligible. What is the tension in the cord?

    2. Relevant equations
    (im not sure if these are right)

    3. The attempt at a solution

    Can you please draw the free body diagram and attach it? You cannot possibly do these problems without a free body diagram (Well, that's not true, but it's a stupid idea to do these without one)

    You just hadn't used the correct tags. You could have just posted the link I suppose.
