Homework Statement
Three objects m1. m2 and m3 are suspended
from three massless and frictionless pulleys as
shown in the diagram. ml is 6 kg, m2 is 2 kg
and m3 is 3 kg. Find the tension of the string
when the system is set in motion (i.e. all
masses are moving). Answer in N.
Homework Equations
Based on the free body diagrams.
The Attempt at a Solution
We had covered this earlier in the course, and I believed that I understood the material. When I tried to do the problem though, I realized that I have no idea where to start since I can't get the righter answer. I set up the basic equations like for m1: ma = mg - T, but that can't be right since you would only need two equations then.
I believe where I am going wrong is the acceleration, can anyone shed some light on this for me? Thanks very much :)
