Four balls are suspended by cords. The longer, top cord loops over a frictionless pulley and pulls with a force of magnitude 95 N on the wall to which it is attached. The tensions in the shorter cords are T1 = 56.0 N (between ball A & B), T2 = 46.7 N (between ball B & C), and T3 = 9.3 N (between ball C & D. What are the masses of each ball in kilograms?
Im not sure what type of equation to start off with this..
would acceleration = 0? .. since the tensions between a ball are in equilibrium?
If the cords are fixed to the wall, acceleraltion is zero.
Start with the tension at the wall, pulling toward the wall. It is supporting four balls.
Then, the next tension
T1= B+C+D and so on.
