A wedge with mass M rests on a frictionless horizontal tabletop. A block with mass m is placed on the wedge and a horizontal force F is applied to the wedge. What must the magnitude of F be if the block is to remain at a constant height above the tabletop?
F=ma of course...
Ffriction = coefficient * normal
The Attempt at a Solution
I know the final answer is (M+m)g tan(theta). This is a practice homework so we were given the answer but no work going up to it
