Homework Help: Tension at the middle of a string of known mass

  1. Oct 10, 2009 #1
    1. The problem statement, all variables and given/known data

    How can i get the tension in the midpoint of a string of mass 2kg that connects two blocks of mass 15kg each if i applied a force 66N to the block on the right to drag the system across a frictionless surface?

    2. Relevant equations

    3. The attempt at a solution

    Hi natnat_nuts, welcome to PF.
    what are the relevant equations you have to use to solve this problem?
    Show your attempts. Draw the free body diagram of each mass.

    my teacher gave us nothing in particular . . . that's why it's difficult. we could use newton's second law, kinematics, work-kinetic energy theorem etc since we have discussed those already.
