Homework Help: Tension in massless string

  1. Nov 15, 2011 #1
    1. The problem statement, all variables and given/known data
    A mass m1 = 5.8 kg rests on a frictionless table and connected by a massless string to another mass m2 = 5.2 kg. A force of magnitude F = 30 N pulls m1 to the left a distance d = 0.87 m.
    2)How much work is done by the normal force on m1 and m2?

    2. Relevant equations

    Δk=Wnet

    3. The attempt at a solution

    I was solving for V final when I realized that tension does work. How can you find the force of tension for this problem without the acceleration? I keep running in circles. Textbooks, etc. don't alleviate the headache. Help!
