Homework Help: Physics problem using Newton's laws how to solve?

  1. Oct 31, 2012 #1
    1. The problem statement, all variables and given/known data

    how do i solve it ? if someone can help I will appreciate it.

    Two masses m1 = m2 = 3 Kg and 5 Kg lie on two inclined planes with negligible friction connected via a cord that is inextensible and massless. The planes have angles of 30 degrees for m1 and 40 degrees for m2.
    a) The net acceleration of the system ?
    b) The string tension?
    c) How much should m2 weigh for the masses to move to the right with constant speed?

    this is the image

    2. Relevant equations

    3. The attempt at a solution
