Physics problem using Newton's laws how to solve?

    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?
