Homework Help: Two masses are connected by a string and pulled along a frictionless surface by anoth

  1. Jan 20, 2010 #1
    17. Two masses are connected by a string and pulled along a frictionless surface by another
    string one is 5kg and the other is 10 kg to which a tension of 40.0 N is applied. The magnitude of the system’s acceleration
    is
    A. 8.0 m/s2
    B. 20 m/s2
    C. 13 m/s2
    D. 2.7 m/s2
    (For this question I added the two masses to get the mass and then I used the equation a=f/m to find the acceleration)

    Is D. the correct answer?
