1. The problem statement, all variables and given/known data I have a block of mass M attached to a cord of mass m on an inclined plane of angle θ . A force F is pulling the cord & block up the plane. I have to find the force exerted on the block by the cord. The surface is frictionless 2. Relevant equations F = ma 3. The attempt at a solution So far I have tried to figure all of the forces that are acting on the system and place them in the F=ma equation. This is what I have come up with: (M+m)gsinθ-F+Fc=(M+m)a where Fc is the force exerted by the cord. Otherwise, I am unsure of how to proceed.
