1. The problem statement, all variables and given/known data For the situation shown in the diagram, the block of mass m remains in place on the sloping front of the accelerating wedge, even though that sloping front is frictionless. Given these values, M = 20.0 kg, m = 4.00 kg, and theta= 34.0, calculate the net force acting on the wedge plus block (M+m) system. 2. Relevant equations Newton's second law of motion 3. The attempt at a solution At first, I tried turning the frame of reference so my normal force for the block was on the y axis on my free body diagram. However, when I was looking at it more, I was confused on what I was actually trying to find with the wedge.
